I'm looking for a little information on a Rolleiflex TLR I picked up - especially around close-up accessories.

My camera is a Bay 1 Rolleiflex, serial 1719847 and it seems to be in fine working order based on the few rolls I have developed to date.

Does anyone have information on the Rolleinar #1 Close-up filter set? I would like to get full-frame portrait shots but the current close focus distance is 3 feet. The lens is a Xenar f3.5...

If you have information on this camera (date made, etc) or the use of the filter set please take a second to post them here.

Thanks,
Gregg Brekke
