Thank you for all of the excellent suggestions. Here's what I did:
Hobby shops have liquid epoxy with the consistency of motor oil with
various curing times. I wanted to backup the hole and reinforce the
cracks with fiberglass. Liquid epoxy was needed to thoroughly wet
the glass fiber; paste glues cannot properly do that. The fabric and
resin was applied as a backing inside the case and I used JB Weld to
fill in the hole. Sanded it down and then applied India ink. I did
not refinish the rest of the casing because it cleaned up well and
has a nice original patina.
Cheers,
John
