The things that worry you are the reasons I would not buy Beveridge speakers and have them restored. While I don't have personal experience with Beveridge speakers I think your restoration budget of $2,500 sounds low. Restoring anything this old is usually full of suprises, and most of those suprises will cost you money, sometimes significant amounts.
If you said you loved Beveridge speakes, always wanted a pair, did not care about the time and money involved in restroation, I would say go for it.
I wish good fortune in your quest.
