I have an old frame you could buy, its your size. Its a nice peugeot fitted with 531 tubes.
Did many fun miles on that frame.
Red, nice lugs, good condition. The only real problem is its got vertical dropouts so you wont be able to build it up fixed. Only SS. I have a chain tensioner too that i could throw into the deal if you were interested in it.
Sorry, looking to build up fixed, nice frame though.
