A standard TA is 18.5 & that's not an expert.

I have an 88 Elf which is 19.5... was told it's an expert.
Whether that's right or wrong i don't know.

Same with MRD Ed, the expert was 18.5" and the Pro 19.5" - they did special XXL frames for Tim I believe that were getting on for 21" but Animal would have to confirm
Standard Mongoose and Supergoose tt length was 18.5" from the late 70's to the late 80's but I have no idea after that as I have no interest after about '84 / 85 frames until newschool
I'd go 18.5" & 19.5" as your answer roughly

due to difference in seat tube angles, BB to top of h/tube is probably where the biggest difference is.

That's a good point!
I also get the impression that tt lengths increased (and therefore the designation of "expert" and "pro" models changed) through the 80s, with many of the early-mid 80s classics (GTs, Skyway T/As, Laserlites, etc) being around the 18.5-mark, and longer versions coming thereafter. Thank god for laybacks!
