34.4" inseam at your height. That's very unusual. Leaning towards custom frame territory.

Assuming your saddle height would be around 76cm+, you'd probably be looking at a frame with a 50-51cm Effective Top Tube, but with a pretty long seat tube and decent head tube.

I've seen the odd old custom Serotta frameset out there with proportions like that, for example.

What kind of bike style are you looking at? (road / endurance / gravel / flatbar etc.)
