1949 Contax S and Sonnar 2,8/18cm against Fed b

Hello,

I want to trade my Contax S 1949 type A s/n 890 with a Sonnar 2,8/18cm s/n 549900V60-2, march 1949, M42 prototype, against a Fed b (1/1000th, slow speeds, 2/50mm lens) of course original.

The reasons: this Fed b misses my collection. I am not such a SLR Contax fan to keep it: other collectors will keep this camera alive much better than me. And I don't sell it because I am very reluctant to mix money and history...
