First three films from my grandfather's camera

He died in the 1970s, and it may not have been used since then: he must have bought in in about 1960 (it's a Retina IIS). The meter was set to ISO 125 so it must have last had FP4 in it. So this is three rolls of FP4+ which I thought would be appropriate. And not only does it seem to work, it does work, clearly!
