With those tanks, it “may” have been a German-built Tip-Top. but honestly, to me its unrecognizable as any brand in its current form. If there are casting numbers on the crankcase parts, it might yield some real clues as to who built it. At that price, I’m going out on a limb and suggest it won’t sell for that, hehehe

He's livin' in his own private Idaho..... I hope to go out quietly in my sleep, like my grand-dad did..... and not screaming, like the passengers in his car...
