Then I guess, I should buy these and sell them on Ebay, might be able to make some money for Christmas...
PS, this converstaion really had nothing to do with Contax, I played, but don't understand why you even brought it up, I remember this being about Olympus OM, or did I read the header wrong????
Oldest OM-2 bodies can be problematic. OM-2 production started at serial number 100,000 and continued to somewhere around 600,000, when production chnaged over to the 2N. I'd avoid any OM-2 below 250,000 serial number simply for the amount of work they need to be made reliable. If it's up around 500,000, perfect, as it's got almost all the improvements before it became the 2N.
