WTD: XL frame for gravel or monstercross conversion

Jumping on the bandwagon but fancy some dropbar shenanigans again. 

Is anyone selling an XL (or similar sized) frame (+- forks) that I could base a project around. 

Ideally something with disc tabs (late 90’s/00’s) or steel retro that I could braze a disc tab onto. Or even something more modern but would prefer to keep the weight down. 

Minimal budget so dusty, scruffy, tatty is fine.

Thanks Chris
