Hey all,

I'm not sure if I have posted this in the correct section but I
was wondering if anybody could help me identify the maker of this
frame / give any suggestions / general information about it.

I won it through an online auction and I have the intention of
giving it a new paint job and some new parts but I'm interested
to find out a bit more about the frame before I start.

Serial Number reads : 74143
It has some 'bi-plane' forks which I don't see very often so they
might have the strongest indication of the maker, I'm not sure sure.

Any suggestions? Could it be a Bosomworth?
Headset threads are italian i believe.

Could the serial number 74143 indicate 1974?

Here are some images of the frame:

I have no idea what it is sorry, but I'm sure it's not a Bosomworth.

You're most likely right about the serial number being related to the date it was made, but sadly lots of builders do/did that so it's not so much of a clue.

The lugs and fork crown look more to me like an English frame than Italian - how do you know it's an Italian threaded headset? They are almost identical to, and interchangeable with, English headsets. The bottom bracket threads would be a better indication, as Italian threaded b/bs are unusual on anything made outside Italy.

I recently sold a frame with similar forks (mine undrilled) and lug work.
Was rode by a NZ junior sprinter 20 or so years ago.
Would take a guess and say its a New Zealand made frame which I'm pretty sure mine was.
But check the BB, if that is Italian at least you cancel out quite a few makers.

Thanks for your help.
They guy I got it off said the headset was italian threaded.
I'll try find out more about the bottom bracket if I can.
Would photos of any specific area help at all?

Thanks Musta, I was thinking NZ made too, which
is why I assumed maybe a Bosomworth.
I'm not sure what to check for on the bottom
bracket to see if it is italian. I know the shell
width is approx 680mm which I don't think is
the standard for italian shell widths.

The headset I have for it is a Tange Levin CDS
and the size is 30.2 - 26.4

Italian b/bs are usually 70mm wide, and the threads are a larger diameter to English (as well as both cups being r/h threads)...

It may well be NZ made, but most likely from lugs and fork crown sourced overseas in either England or Italy.

If you don't have BB cups to check an Italian BB diameter will be 36mm vs. English 34.8mm.
An english bb cup will therefore not even bind/touch the threads properly

Cheers I didn't know that.
Going to go with the English Diameter for the BB.
Guess that doesn't narrow it down very much haha
