Smoky. My brother is the owner. He paid $25 to a farmer. He had two in a barn. He took the black one. It had Mohs stickers over the whizzer tank. He took the bike with him to a motorcycle show. He had a motorcycle that he use to show and he brought the bike with him. An old man came up and said “you have a whizzer” my brother said “no it’s a Mohs” the old guy said “no, it’s a whizzer, I’ll show you” he pulled the stickers off the tank and it said whizzer under it. So my brother thought it was a whizzer all these years until I got it. So some old man pulled the original mohs stickers off the tank. Ugh!! Does your tank say whizzer? I noticed in his book that he used a whizzer tank and put his graphic over it. Bruce Mohs was a different character that’s for sure. This is the book about him and the picture of how many were made along with a motorcycle with sidecar/boat. He said in his book he made most of the bikes on his kitchen table.
