Lenses for review needed!

It's time to start looking at some more vintage reviews. Several members have kindly loaded lenses of interst to enable some past reviews, so if anyone has anything of interest please let me know, either here or in a PM if you prefer.

I am particularly interested in the K and M series lenses, and the 50mm f/1.2 would be a great start if anybody has one?

I can cover the cost of shipping and lenses are fully insured whilst in my possession.

Many thanks!
