Axel Merckx, Eddy's son, has a similar build--all arms and legs. Eddy and I lean in that direction, but not as bad. I'm 5-11.5 with 35" legs and a 75" wingspan. In modern bikes, I've found 57-58 cm fits well if the top tube doesn't go over 57 cm. I have a '80 Masi, 60 cm with a 57 cm top tube, that fits me perfectly. With the seat clamp reversed it looks like your upper body position is quite vertical and your leg extension is a little short. I'd venture to say you could get more leg extension by moving the saddle back. You might also get more power and better handling with a lower back angle and lowering the stem. Start with the shorter stem, then see if you can use the longer one without crabbing to the front of the saddle as you ride.
One advantage of those old British frames for you is the top tubes on the taller sizes tended to be shorter.

Case in point, a tall British frame with a short top tube. The proportions for the International are more conventional.

Naughty thread bump.
Here's another UK frameset. 531c.
63.5cm / 57cm with a 21cm headtube.

Finding these type of frame proportions is a bit of a hobby of mine.

I ended up measuring both ways because some videos/sites said with shoes and some said without. With shoes it’s 36” and without is 35.5”.
The way I have the Dawes set up right now is actually pretty comfortable so far (longest ride on it like this was 40 miles). Since starting this thread I have changed quite a bit, but the seat post height was risen because I was having some knee discomfort when it was lower, but that was also before I changed the crankset so I might play with lowering it a touch.
I think the Dawes is 98% set up perfectly, my bigger issue is that I’m trying to upgrade the frame to a nicer one and I’m struggling with what size or geometry to look for with long limbs and a short torso. I’m thinking anything I could make anything from 58-62cm work with the sweet spot being around 59-60cm C-T? But that’s really just a guess. The Dawes is 62cm (24.5”) C-T as a reference point.

I've looked at an awful lot of old geo charts, and I have yet to find a common production road bike with the legendary "criterium geometry" compared to today.
