Well, I think I have been spoiled with the items I have been getting lately (like the one with the original paper tag)! I did paint a B30 that was in horrible shape (the top was actually stripped to brass) and it came out pretty good from the rattle spray can.
Luckily I have a "spare" whistle base with handle, so I am good for that part that is broken on it. You are correct, having the whistle topper and stack is in the plus column for sure! We'll see how well it will polish out but I seriously doubt I'll try to repaint it. I try to live by "do no harm" and when I deviate from that mantra I f**k things up LOL!
One thing about the base, it seems to have 4 extra holes. From all the eBay photos I really can tell if the are OEM holes, they seem to be but I don't recall a Empire base having these 4 holes (it has the other normal ones, so that is 6 holes total on the base). Very strange that someone would drill more holes into the base but then again people do strange things!
