For $99.00, I am very happy with my newly purchased Falcon Black Diamond frame.
Upon receiving the frame I did notice that it needs alot of cleaning up before she hits the road again. One of the things that stood out was the fact that there is a brace behind the bottom bracket that doesn't quite look like it belongs. The welds in this area are not as clean and there is a small gap where the brace does not exactly fit. Judging from the worn paint patterns it looks like the previous owner had a kickstand mounted in the area and maybe they added the brace to accomodate the stand.
I plan on bringing her in this week to get repainted and possibly have this bracket removed. I also want to have my local vintage bike shop take a look at what kind of components will be compatible for the frame since I have not found much info on the web. So far the only thing I have figured out is that it has 120mm rear spacing.
Here she is:

It certainly would have had a chainstay bridge originally, but it does look like yours is very crudely finished or previously repaired and perhaps falling off. Might be time to visit the framebuilding shop.
It is meant to be there and is called a chainstay bridge. Its puropose is to stiffen the rear triangle with a secondary purpose of providing a fender mount. It was a common feature on almost all bicycles until the mid-1980s when special bottom bracket designs, shorter chainstays and stiffer tubing started to eliminate it.
From what I can see, you have a repainted, boom era frame. The heavy consumer demand for bicycles during this period resulted in a lot of shoddy work. The presssure was on to get the product out the door. Framebuilders were being asked to speed things up and were tired from lots of overtime. There were also lots of new employees. Inspectors were being over ruled on workmanship that would not normally be acceptable. It was not a good time for workmanship, especially on bicycles coming out of Europe. The workmanship was widly inconsistent and it was not uncommon to inspect 5 or 6 identical models to ensure you got the one which had the best workmanship.

That looks just like the bridge on my Carlton. I always thought it was a crude looking piece, but the frame is double butted Reynolds 531.

Looks about like the tig welded stuff that is coming out of the far east these days:rolleyes: Glad to see that QC was alive and well then too:D
Nice looking frame BTW.

I think it should be a fixie...Look at the lack of braze ons...perfect! put a set of Cane Creek Volos tubular rims and, a modest crankset and be on your way. Nothing says cool like a rusted steel fixie that weights 18LBS.

Thanks for the replies. The owner of my local vintage shop is an excelent frame builder so I'll see if he can clean it up a bit.
Anyone have any ideas of what kind of wheels she should take? I tried to fit a 700c tire in there and it looks like it fits but I just want to be sure.

Heres a few pics of the one I just sold, maybe itll help :)

The chainstay bridge doesn't do much structurally when a rear wheel is in the frame. If you have it repaired, then be prepared to lose the paint all around it, since the heat will take care of that. Otherwise, just be careful when handling the frame without a wheel in it, and it shouldn't matter at all.
If you want to know what size wheels to use, measure from the center of the axle slots to brake mounting hole on both frame and fork. A typical 700C wheel is about 311 mm from axle to center of brake pads, and a 27" wheel is about 315. If more than 57 mm brake reach is needed with 700C, you may have trouble finding calipers long enough easily; and a 27" wheel might make the difference. Also be aware that, if your bike is d'un certain age, you will probably find that the rear brake reach required is longer than that on the front. In that case, centerpulls are probably the answer, in two different sizes, like the ubiquitous (for us anyway) Weinmann 610 and 750 models.

The butting looks less complicated here... any ideas what the year/model/tubing is...?

Actually, aside from the sloppy brazing on the chainstay bridge, your Falcon doesn't look bad at all: I like how the headbadge fits "just so" in the gaps left by the head lugs. Seems to be a "flamboyant" purple over silver metallic undercoat, and the purple has nearly faded completely away! At least the pump pegs are intact :)
I have a similar one in the same transparent purple. Yours looks like the purple has faded to the silver base. The chainstay bridge looks original. From the seat cluter design, pup pegs and lugs I'd guess that earlier than bike boom; from the 60s? Model seems to be "Black Diamond" on the chainstay, maybe that will help in identifying.
Headbadge does look put on with pop rivets...
Here is a Falcon which I restored last year. Previous to that it was a mess, rattle can paint job, etc.
Most of the parts are original, with a few period. Circa 71.
