Not been around this part of the forum for a while, but got me thinking about lenses etc I have that aren't mounted. So I dug the old stashes of lenses and rubber out. Most of the lens boxes have two pairs in, rather than just one, I prefer them boxed up like that to having half of them loose in the foam sleeves. I'd forgotten I had that much coloured rubber too
I'm sure there are people with bigger stocks of OEM parts than I have, so show them off here!
