Please see the profile. Retina, 29.5mm diameter for Agfacolor 32 -oL I bought it as a spare, but I never used it and kept it in the box, so the glass surface is almost pristine. The "r" in the "Germany" text in the photo has black missing. I haven't seen it much on the market recently. Don't miss this opportunity. (Note) Retina body is not included. No returns or exchanges, please.
