Before I start buying new, I thought would ask here. I need to get hold of some slide trays like the picture attached.

I now have my father's slide collection from the last forty years but unfortunately they are all in an old style of enclosed tray which doesn't fit in the new projector which he bought shortly before he died.

I just need the trays, not bothered about the storage enclosures but if you have them as well I will consider them as you would probably have no use for them without the trays!

Probably UK only as the postage costs may end up higher than the value of the parts.
