I'd like to pick up some of the 4x5 holders with the little number wheels on them. I have a few and always thought they were Riteways but one is also marked Lisco Mark II, so maybe there are several varieties. The ones I have also have the little button that locks the dark slide in place and not the normal wire things. But mainly I'm interested in the number wheel feature/curse/however you see it. If you have some to sell, PM or email me, please. If you post here, I don't always see it or get a notice. Thanks.
