Want to Buy WTB: 50mm lens for RB67 or 500cm

I would really like to find a decently priced 50mm lens for one of these two cameras. I don’t mind rough lenses, as long as it functions properly and the optics are good.

Please message me if you have something you can part with.

I have a lens you are looking for but I am in South Africa

Thanks Ben, but I'd rather stick with someone with an APUG/Photrio history because of the money involved.
