I did a little looking into this a while ago. Like telescope mirrors,
the prisms are coated with aluminum in high vacuum. There are shops that
do this stuff for amateur telescope mirrors. With a batch of prisms, one
might be able to get them all done at once at a reasonable price apiece.
Glass to be coated this way needs to be specially cleaned and one would
have to mask the 'in' and 'out' surfaces. I never went beyond seeing
what was possible to checking actual costs, etc. I could certainly
contribute some prisms if someone arranged a group 'silvering'.

Ok, so what to do with several dead OM-10 bodies with (now) mottly prisms ?
Are donor bodies the only source of prisms or are they still available from Oly
?
Haven't been available new for many years.
