Ha - posts been edited since I asked!spain, it says on the profile thingy just to the left there.
I have the remains of a 35B - in one piece except for top cover bits. The lens etc is intact. IF it's the same part on the 35B and IF you want to cover the postage to Spain (I'd have to find out what it is) I could send it to you for just the cost of the postage. PM me if interested.
