Great find!
Great community support on identifying it!
Is it a 531 butted or straight gauge? I couldn't discern the decal type.
Thanks.
Good question
@Jesper.
It can only be one of two 'Reynolds 531' transfers that were available at that time, shown here in an excerpt from the 'Reynolds' tubing timeline on 'H. Lloyd's' website.....
...I'm basing that statement on the position of the "531" in relation to the "Reynolds" wording. it's just a question of the size of the extant transfer on
@corbettclassics frame to determine which one I will need; both examples are readily available to buy.
This suggests that it is plain gauge tubing and the internal diameter of the seat tube is definitely not 27.2mm on mine which kind of rules out double-butted tubing.
Although this can be a very grey area of much contention as I believe some manufacturers (Raleigh are well known for this) used seat posts of 25.4mm on some of their double-butted 'Reynolds' frames.
This transfer also suggests that only the main triangle is 'Reynolds' tubing.
From what I can gather about 'Uppadine' is that they were very much built to order, for the discerning, serious club rider; and those aspiring to be so!
Here is their advertisement that ran in 'Coureur' magazine through the 1960's.....

..."100% Light and Ultra Light specialists" no less.
I'm now curious as to which TdF riders they built frames for.
Apparently there was a photo hanging on the wall inside that shop showing a certain T. Simpson riding one of their machines!
