I think so too, Michael, but to my surprise I found that the varnish on the recently purchased RCA 9K strongly conflicts with nitro solvents and I could not varnish its top cover with nitrovarnish.
Is it really covered with shellac?
Could it be that at that time there were still some unknown types of varnishes?
Is it really covered with shellac?
