A replacement bezel for the WW2 Air-Ministry RAF JAP-2A Engine charging set.
I restore Stationary engines for a hobby, sometimes parts are broken so I measure what I have and attempt to reproduce parts so they can work again.
This is something I measured up designed and reproduced.
Will require a Dia.47mm x 2mm glass.
Photo shows the original.
