Adapter for pentax lens

Hi folks, do any of you know where an adapter to mount a pentax lens on a panasonic gh1 (mft) can be bought other than fleabay. Lens has aperture ring and will be left in manual focus so its really just a basic adapter i need.
My brother in-law wants to borrow my 100mm macro .
Hope you can help

Regards
Derek

You could make it easy for him and lend him a decent camera too!

It could even be just as cheap for him to buy an older Pentax!

I bought mine off ebay but you could try the people at srb-photographic.co.uk who have them in link

Perfect Walt, Sorry. Perfect, Walt.
Thank you.
