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?
