My Rolleicord is usually attached to these strap ends. But it's away having a service - or a CLA as people tend to say on photo forums. Clean, Lube and Adjust. Hopefully when it returns on Tuesday it'll go click-zzzz-click on the long speeds instead of click-zzz-z-zzzzz-z-z-cl-ick like it has been recently. The good news is that these old Rolleis tend to go on forever with the occaisional service, the bad news is that it's a bit out of guarantee, as it was purchased in September 1970... oh well.
