This listing is for an empty brass microscope objective lens canister by Henry Crouch probably dating to the early part of the C20th. It's marked as follows:
- 1/12th inch Oil Immersion
- H. Crouch, London
The canister dimensions are - 40mm high and 26.6mm internal diameter
There's no objective lens inside - it's just the empty brass canister that's offered for sale.
The canister will be well wrapped and shipped by Royal Mail.
Thanks for looking.
