Mystery Lightweight Frame Find Today 50s??,Anyone Help

[cipolinni]

Helo guys
Picked up this rather nice vintage lightweight frame today,painted by brush poorely,have removed some paint to reveal either a black or dark brown finish.
No holes for headbadge.
Hopefuly the Forks to match will surface from his vast collection,waiting on a call to search for it in his shed.

It looks like an early 50s frame,very light,pencil thin seat stays
Nervex Pro Lugs
Underneath the BB shell is engraved "Nervex"
Aswell as frame number 59 3064 022 E38
Also 290 on LH rear dropout
Very nice rear dropouts,but cannot see any engraving
Weird looking braze-ons on the rear seat tube,Downtube bosses for drinks bottle cage?

Please see photos for reference

Looks a highly skilled frame build

Hopefully someone here can shed some light on it's brand and frame builder.

Nervex pro lugs, as used by hundreds of small and larger frame builders. Looks mid 1950's to early 60's. The numbers refer to angles etc.
Rear ends being pressed would tend to suggest earlier, as forged ends almost replaced them by 1960. Odd what looks like a brazed on boss for a CO2 gas or compressed air pump, so was a serious road racer.

The boss behind the seat tuibe is for one of these -

The pumps are relatively easy to find but the single Terry clips to hold them are quite rare.

Not sure you will nail the original builder...

I used one but not very successfully. CO2 leaks very quickly, and also the cartridge tended to freeze, making it difficult when you needed two. I have an Edco compressed air here somewhere, but refilling was difficult, also rather heavy.

Strange you should mention EDCO......they produced a really nice headset in alloy about 1976 and then a cracking bottom bracket about 2 years later.........

then vanished

I had an Edco alloy headset in my 1977 Argos, equal to anything then.

I have an EDCO alloy headset on my Bob Jackson / Kevin Sayles 70's TT frame, we sold them in Gold and silver so I chose a silver one....

Still doesn't hide the fact that they are massive LOL

They're still around, believe it or not - at least, their website is still live:

They were bought by SAPIM a few years ago, and continue to make hubs and wheels for the European market. I had a pair of their fancy mtb hubs quite recently.
