25.5 inches, or 64.77 cm, c-t. Tall Raleighs were somewhat short in the top tube, though. It could be a nice frame for the guy with long legs and wants to keep the handlebar somewhat level with the saddle.

Regarding the Brooks B-17. I only got $55 for mine, and it was in better condition than that. But for $75--well, let me say I've seen much worse bikes sold for three times as much.
