It's possible, I think, that someone could put a hole in the tube to match up with a hole in the lug but why? It might weaken the frame and even if you expoied some sort of gem in there you run the risk of it falling out and then the frame can get dirt and moisture in it. Others will correct me if I wrong but I believe putting a hole in the lug is not only decorative, and helps identify the builder in some cases, but it aids in getting the solder flow through the joint better.

ALso why go to all that trouble and not put a makers mark of some type in the seat stay caps and fork crown?
Thanks Bianchigirll! So I know who the framebuilder is, a fellow named Fritz Loudenslager who had a shop in Ketchum, ID. I even have the original bill of sale. And it looks like 501 cro-mo, which I believe was a step below 531?

I will share more about the bike and its story. I just got her from the original owner yesterday and I only replaced the saddle for a quick test ride. Everything is in excellent condition, just gonna replace the hoods, housing, bar tape, and straps.
