Unknown 50's road/path build

Devout Dirtbag
So, with Eroica only a few weeks away, it's high-time I started putting together a steed - I've ridden the last two on 80's bikes, first with standard 'racing' gears and last year on my tourer, which almost felt like cheating as I spun up Mam Nick in 34/28..
The inital idea this year was to take the tandem, but that was shelved due to the hassle of getting it there by train, and instead I've taken it as a kick up the arse to get on and finish the 50's road/path build I've been slowly accumulating parts for over the past year and a bit..

The frame came to me in late 2014 from A Certain Well-Known Purveyor Of Vintage Frames & Parts, and was of unknown pedigree, though described as having 'Mercian-like' features. Here it is shortly after arrival:

It's a decent well-made frame - 531, Serie Legere lugs, nice ridged seatstay caps - but the lack of a frame number or any original paint has so far put paid to identifying the maker, despite a few names being floated in a thread here.

My initial intention was to not be too precious and just build it up with parts I liked rather than go for a full period build but, as usual, that idea lasted about 5 minutes.. Nevertheless, I stuck a load of beater parts on it and rode it as a winter knockabout in the guise below whilst researching and locating suitable 50's kit..

Skipping forward a year or so, I've gathered almost everything I need, and with the Eroica-Tandem plan ruled out, the frame was boxed up and sent to Bob Jackson for some minor tlc and a respray. Skip forward another 4 weeks, to a few days ago, and this was sitting in front of me:

And once unwrapped, here's what we've got:

As is often the case, photos don't do full justice to the colour here - it's a gorgeous Burgandy Flam rather than muddy brown. Looks even better under sunlight too, and though that had disappeared by the time I took these pics, the flash in the photo below gives a hint:

That's a classy looking frame, love a nice Flam :). Have you had a new seat bolt brazed on?

Thanks, I can't stop gazing at it :) and no, the only work was a retracked rear end and couple of filled dents.

Now though, it's time to open up my shoebox full of parts.. The vision I've had for the bike is a late 50's/very early 60's style, my best guess as to the frame's era - a mix of classic British parts with some choice picks of the kind of new-fangled continental kit a forward-thinking clubman might have gone for.

First off is the headset - a TDC 'Italia', which debuted in 1960.

My first period-incorrect infraction comes thanks to the crown race, as the original was brinnelled. A root around in the loose parts box brings up a JIS Tange race which fits nicely, even if it is black. Not to worry, it's practically invisible once fitted.

BB next!

I've not been able to find the year the TA introduced their bottom brackets, but it's not unreasonable to assume it's alongside the Pro Vis cranks c62/63. Slightly late again (and this NOS 314 is certainly later still) but I'm going cotterless and it's the next best thing to a 50's Stronglight..

Hi anagrama,
Wonderful project, I love the colour and the seatstays are exceptional. I will quote you here, "My first period-incorrect infraction comes thanks to the crown race, as the original was brinnelled." that tells me you are very familiar with machinery as the term "brinnelled" is not common outside of the engineering community, good on you :D .

Ah! The good old discussion wether it's fretting or Brinelling :)

It needs some decals to finish it off, and the removal of that Bob Jackson sticker :)

Maybe a "shop" decal might work?

Shaun
 
Nope, no engineering background - I think I came across the term soley in relation to headsets :) And also see that it's possibly incorrect (as was my spelling!) as Midlife hints..

Decals do pose a quandry - 'shop decals' are an option like you say, but I'm happy leaving it be for the time being at least.
I did briefly think that the restoration had uncovered a previously-unseen '174' frame number on the steerer tube, but after checking the paperwork (and finding another under the BB shell) I see that was just Bob Jackson's internal reference.
The respray did, however, reveal an RGF logo on the BB shell that I hadn't spotted before - doesn't really help identify the maker as they were commonly used, but it's nice that the frame itself matches the Anglo/French mix of parts I'm using.

And on that note, the cranks went on today - 49D's with a 47T 3mm TA ring, both with the correct 50's markings:

Note lack of BJ sticker too :)
