Retina 1a filter thread?

Hi, I have just bought 2 X Retina 1a's. Just need to know the filter thread. Is it 21.5mm or something else?? Thanks

AFAIK the f/3.5 Xenar lens takes the 21.5mm screw-in (27mm push-on) filters, f/2.8 Xenar lens takes the 29.5mm screw (32mm push-on) filters.

That's great. Thanks for the information!!
