I don't think you have anything to really worry about. I have a kit where the toms are painted inside and the bass is not. My bass drum has the date stamped on the inside, where the toms do not.
Hal Leonard I believe, published a book on the history of Leedy. I have not read the book in it's entirety, but they usually have information coming directly from the source, whether its from people who worked with Leedy, or people who were involved with purchasing or selling the company, even some people who just played Leedy kits back then. They are usually very well written books.
You might want to get a copy of this book, and read it with a 'grain of salt'. You have to remember that we were either at war or just coming out of war in the '40s and supplies were hard to come by. Ludwig I know, was notorious for using any and all hardwoods he could get ahold of cheaply.
Also remember, that the idea of a 'drumset' was still a very young idea. People still weren't seeing the best way to make these things (today they still struggle). Judging from the pictures, you have a very nice looking drumset. I don't know what you paid for it, but somewhere in the purchase you were fine with the price for what you were getting...don't forget that. Is there any real value in these old kits, who knows. If they were so great, why did they go out of business, change parent companies, or even change the way they made drums?
Best of luck to you, and your collection.
