A few low value odds and ends for swap?

I have the following which have been sat around unused for sometime, before they go to the charity shop I thought I would see if they are any use to pentax users.

Standard pk adaptall mount

Non branded m42 on mount

52mm reversing ring

2x t mounts

Swap one or more for me super body cap, sd memory cards etc.

Also a 52mm circ polarize filter, hoya brand boxed an unused.
