That font and location look like a Raysport serial number to me (and 1039 or whatever that number is, is about right for a 'late' Raysport). If the rear drops have the brazed-on inner washers, it's a Raysport. The fork looks Raysport too.

Check the fork threads - should be BSC. Not sure why the BB is French. If the fixed-cup side is left-handed, that's Swiss, and someone may have forced Swiss (alloy?) cups into a worn steel BSC shell.

Ill check for the washers on the inside of the rear drops,also i'm pulling the head set to see if its French too! the crankset is from argentina saavedra? any spindle requirements for that crank?

You could just measure the steerer ID if you don't want to pull the locknut, but if it were me, I'd pull off the locknut to check the thread ID, as sometimes French steerers have been reamed to 22.2, over the decades....

Almost to 50.... :-)

too weird, but obviously a nice frame: the 26.8 post might show up on a late Windsor using Tange tubing from Japan, but this doesn't look like one. BB could be 68 and BSC, but again the details are wrong, incorrect serial number location for one... never heard of Raul Garza's name applied to Windsor, they always were Acer-Mex products, AFAIK.
If this is correctly ID'd as a 35x1 BB, then all bets are off. Might be some obscure Argentinian make, and a fairly nice effort I'd say.
Do the tubes have standard ODs or do they have metric dimensions?

i'll be checking od's of the tubes and it's a Mavic 360 stem,I'll pull it and if its 22.0 then all threads match. the argentinian crank is saavedra?did they make bikes?

Saavedra drillium!! even the teeth are drilled,very pretty!!

Very cool. How wide is the BB shell (or are you not at the bike's location yet)?

I'm sticking with my vote for Raysport at this point, pending only the washers-on-the-dropouts issue, but the tube OD question is a good one (i.e. metric vs. Imperial tubing). A special Raysport, one that had more finish work and a solid, uncut BB shell, because it was going to be fully-chromed, but a Raysport nonetheless. It could even be French-threaded if it is a special (or employee) build. I once saw a 753 Raleigh Team Pro that was factory-supplied with French threads.....

Among other details, the chainstay bridge looks just like the one on the Raysport I am currently holding, and unlike a Cinelli or a Windsor one. I suspect that the seat post is undersized, and sometimes Raysports needed a bit of reaming to get to 27.2 anyways.

I'm off tomorrow and will be measuring and looking for the washers inside on the drop outs etc,thanks guys,Brad

I will verify with Raymond later, but I believe the serial is too high for Raysport. Also no R in the BB. Most Raysports Super Corsas were fully, if poorly chromed.

Brad broached a possibility with me that I shot down, but who can really say. Ian Alsop did build some frames that were pretty much Raysport knockoffs, but the only ones I am aware of were pista.

FWIW, Raymond finds the interest in Raysports rather mystifying.

I've even seen an NOS f/f go for $500-plus on eBay. Really surprised me....

I don't think that s/n is out of the realm of possibility - I've seen pretty high three-digit ones, iirc. Let's see what Brad comes back with re: washers on the rear drops, BB threading/width, and fork threading. I'm thinking an employee's frame, or one that Ian made, or a special build for a specific customer. This isn't a painted one that had the paint stripped, it was polished and chromed intentionally.

Yeah, I blew the seatpost part of the ID. Which considering I owned a genuine SC is a big "oops."

Argentinian copied everything, never crossed my mind that it could be an argentinian copy of the cinelli. In argentina back in the day u were able to find tubes, lugs sets, drop outs, the whole saavedra group from head to toe, aero rims, they had like 3 brands of really really really really good tubulars (liked them more than italian ones). So why couldnt be an argentinian rip off or somebody's home made bike, chroming in south america is super cheap too.

here is the washer some of you mentioned.the headset is french and has no spacer(stack height) I cant find my caliper to save my life?I am going to go measure the bottom bracket shell and od of the tubes.thoughts?

Guess that "washer" clinches it as either Raysport or Ian Alsop...why the French BB and HS is a mystery unless you can get a response directly from Ian or Raymond.

bottom bracket is 68mm and the bottom bracket is saavedra too.it looks like the tape measure says 25mm top tube and a 28mm seat tube o/d,the seat tube lug is thin and has the 26.8 zeus post(long by the way) in it.I also measured the tubes on my Gran Jubilee,a 3 tubes 531 all french bike,same width? that post 26.4 the seat lug looks thicker.may be Raymond or Ian can be reached for comment?help?

As I suspected, a Raysport (or at least ex-Raysport-shop).

Your frame's tubing is Imperial (inch-sized) as opposed to Metric (mm-sized), so your TT is 25.4mm O.D., and your ST and DT are 28.6 mm O.D. That is correct for a Raysport. Metric butted 531 tubing would take a smaller post (26.4 or 26.6) and the TT would be 26.0 mm in O.D., plus the ST and DT would be 28.0 mm O.D. The reason we asked about the tubing diameter is that, typically, a French-threaded frame would be built with Metric-diameter tubing (but not always!).

I think your seatpost is the wrong size, and that the seatlug has probably been smushed a bit around that too-small post. If it doesn't slip or look too weird, maybe do nothing about it, but you might want to consider (very carefully!) spreading the lug ears out a bit, and having the ST reamed to 27.2 mm I.D. at some point.

Cool bike!

I have made a mistake and the threads on the fork are english.I pulled the bike apart and the fork steerer says reynolds 531 butted on it.I found up inside the fork a plastic bag that was rolled up neatly and had a receipt from the bike store it was bought!It has that it was custom made for a lady in daytona beach christmas 1978 with phone number etc?it was bought at Seebreeze bike shop in daytona beach,anybody know if they were a Raysport dealer?

Here's what I found in the steer tube of the Raysport!! any body know of this bike shop?

Bingo. Check the BB threads - they may be British, and a Swiss-thread BB was forced into it. If the cups are aluminum, there may not be much damage to the steel BB shell threads, and you can go back to a correct BB in there....

I have a park tap tool ,as wellI think the bottome bracket is lock tighted in for sure and it came with the bike,I trying to talk to the women that had it made,I will call her son tomorrow,Brad

Carabela?

That is the other brand associated with raysport,Raul Garza,Ian Alsop ? RIGHT
