Thornton-Pickard Imperial Pocket Camera No. 0, 1921.

Thornton-Pickard | Imperial Pocket camera No. 0 | 1921.| Quarter Plate.
Catalogue No. 0215.
These cameras were labelled only "Imperial Pocket", although a thousand or so permutations of the basic camera were made, some to special order only. Reading Tom Holliday's descriptions, ("Thornton-Pickard Cameras & Equipment" the main work on these cameras), I am identifying this one as a No 0. from 1921, because of its wooden drop baseboard and the pillar focusing pulls and curved front support. There is no geared focusing, and no rise or cross movement on the lens panel.
