You are right, it is everthing else than easy to find high quality retro bikes /frames at my size these days. But with some stamina one can also find an old bike that fits well after a while: Today I possess 2 Rocky Mountain Hardtails and one Kona, all in 21" size and model years from 91' - 93'. It took me years to pick them up.
I also know Juchem and his big & heavy man frames, but afaik he has only specialized himself in this niche of big/tall frames about 10 years ago or so. Unfortunately I haven't yet seen an XL size Juchem Serie 1 frame that was still manufactured in the last century. As a modern bike I ride a tailormade tall Nicolai frame.
