I have a lightly used Yashica 635 TLR for sale. Introduced in 1958, this model was a dual-format model, and could shoot either 120 or 35mm with the adapter kit. The kit alone goes for up to $100 on eBay!
Both camera and adapter kit are in very good condition, 90% or so. The 35mm take-up spool in the adapter kit is actually from another make of camera - not sure which - but it works with the 635!
Asking $200. This price includes S/H to the lower 48 states. S/H to other locations will be extra.
