I've considered bidding on this camera, after seeing the thread, but I'd add a note of caution.
My Rolleiflex 3.5E is mint, made 61/62, I knew the original owner who put less than a dozen films through the camera from new, he bought it while in the RAF tax free (35% luxury tax then), but he'd not used it for many years and it didn't work despite therte being nothing actually broken.
As Andy K says the 1 sec is sticking on his Rolleicord, this one may be similar, these cameras shutters etc need use or the lubricants etc on the wind and shutter mechanisms dry/harden and the whole camera needs a CLA.
So if bidding on this one I'd assume it needs a CLA and that may run to nearly a £100, if it doesn't and there's no problems then that's a bonus.
