A box of vintage plates and paper

In my post 'Recent Glass Plate Work - part one', I speculated that vintage photographic plates are a finite resource. The size of this resource is a great unknown, and I mentioned in that post that boxes of glass plates appear frequently in online auctions, generally singularly, or sometimes in two or three. However, a recent successful bid yielded a box worth of vintage plates, films and papers - exceptional enough to write a post about - which arrived yesterday and should keep me in glass plates, along with those I already have, for several months. Dating the contents from the label designs of the various boxes, most of the plates are from the 1940s to 50s (it's possible some may be from the 1930s); the flashbulbs are from the 60s.
