Roberts Slide Archive 1960

 I have received the original Roberts slide archive still in their slotted carousel housings, all 10 of them, which potentially add up to 1300 slides. However not all the slots are full but there are other containers full of slides, as well as envelopes full of slides.  There was a big project some years back to get this lot digitised and my copy of that archive is dated from 1960 and there are around 1000 digitised slides in it.  The originals are similarly dated from 1960 but it seems not all of them were digitised. EG the first one I plucked from an envelope, has a slide of me aged 2 taken in 1957, before the start of the archive. So I will be taking a thorough inventory to make sure all these slides have been converted to digital. I am not sure where my digital slide converter ended up. I think maybe Tim got it to do his old slides.
