This is a historical curiosity.
a friend has had a relative die recently and amongst a wealth of other things photographic, is a large heavy package tied up in preservative waxed paper with the attached labels pasted on.
Anyone know anything further about what it is ?(if someone tells me it's a set of 8½" condensers from a Leech Type B enlarger, that won't be "further information", by the way)
In case you can't quite read the red label, it says "Not to be opened until required for use ... or renewal of desiccant"
