1935 Buck and Hickman Catalogue: Other objects.
Abtus Track drill: A drill that slides along a track:
Sleeper boring machine: This boring machine can drill two holes at the same time into railway sleepers.
Kent's knife cleaning machine: This would have rubbed a mildly abrasive powder over the knife blades when the handle was turned.
Inspection mirror: This is here just to illustrate the variations in prices (in that some things are relatively cheaper, others relatively more expensive). A similar mirror today might cost just £1.
Wooden garden wheel barrow:
Vidal high power electric drill: This is one of the few electrical items in the catalogue.
