Mystery Track Bike ID #1

I picked this up locally with some other track frames and parts and trying to ID the brand. I am not very knowledgeable about the track stuff so if you see any specifics that might point to a certain maker I would appreciate the help. This frame looks to be high quality with the long point lugs and campy ends on front and rear. English thread on RGF stamped BB and fork. The serial number of the fork matches the frame so it is original and might be the key to the ID. Fork blades are round. The suntour superbe pro wheels and crank were in the lot and not necessarily period correct for the frame. The stem and bars are also interesting. The stem looks somewhat similar to some salsa stems that I have had but there are no markings to suggest that, just purely looking at the joinery. The bars are chromed steel Sakae pista bars that are stamped NJS.

Since it is english thread I am thinking British or American. Does the serial number or details match any makers that you can think of?

Nope, but I am with you on thinking perhaps British, based on nothing more than the style of serial number stampings, which look similar to some others seen on Brit marques (such as Holdsworth/Holdsworthy)...that plus the RGF BB shell, not nearly as popular with American builders as the Brits. But I got nothin' more specific.

Forgot to mention that the seat post measures at 27mm on my digital caliper.

After looking up some examples of Holdsworth bikes it seems like this might be the right track. The serial number font looks similar to other Holdsworth bikes I can find, and 42469 fits within a 1975 serial number range which could be correct. I can only find one picture of a 1975 Holdworth Pista and it is fuzzy but the details look similar. Anyone have one that can share better pics?

Still looking for info on this. I have been looking for the fork crown to narrow it down and this is the closest I can find. It has oval fork blades but still similar

Found a better picture of a 75 Holdsworth frame and I donít think thatís it. The seat stays wrap around on the Holdsworth and the fork crown is different, so now Iím back to square one..

keep in mind the possibility that serial could be a date as in April 24 1969

crown: possible it may carry a manufacturer's marking on the underside

a practice followed by EKLA and Georg Fischer

I am now thinking it might be a Mercian Track bike from 1969 (#424 bike made in 69) The serial number would go along with their typical standard and I found an article mentioning that they used RGF bottom brackets. Still looking for a picture to match to though. All the Mercian track bikes I can find look different than this one slightly
