camera's by
J. Lancaster & Sons, but camera type is unknown, probably The Instantograph.
Other members might report which type of Lancaster camera's would match these holders.
extra info:
Typically this holder does
not have any numbering to distinguish the film or plates!
Also peculiar is that this holder does have hinges at the sides as well as at the top!
At the inner side bottom edge of the holder a little 'V' is stamped.
At the sides the holder has (similar) rims at the edges and in the middle (see 2nd picture).
