Regarding display cases

[TheAce]

Hello all, I've recently acquired an antique revolver and I hope this forum is the correct place for this. I want to store in a display case with a glass lid so I can show it without people getting fingerprints on a 130 year old finish.

My main question is about retaining the gun and a few accessories. I've found a display case that suits my needs and it comes with foam insert that can be trimmed, but I've heard foam holds moisture and is detremental for the finish. Any truth to that? Should I avoid the foam for another method? And if so is there anything to keep it decently nestled so it won't bounce around inside?

Thank you.

Avoid foam.

Keep the gun oiled on a rack.

I agree to avoid foam is a general rule. But you don't have to avoid a horizontal display case.

There are many types of foam. Latex, polyurethane, polyamide, etc. Cheap polyurethane outgasses and breaks down. You could cut out of something stable and line with a gun-sock like material.

See NRA museum website. Plenty of guns in cases. Some in cut outs. Why not call them? http://www.nramuseum.org/
