First of all welcome to The CABE. I am not a guru, but as I see it. All the following is good stuff. Looks like a nice bike. J model according to the serial number on the motor. Has embossed Whizzer tank, Hall bi-lite head light and tail light. Also has the Hall 49 generator. Front drum brake. Big Whizzer seat, may have the Whizzer stamp on it. Front fender tip and bumper trim. Looks like it just needs a soap and water cleaning, little degreasing and servicing. Probably clean fuel lines, carb rebuild. Needs points cover. Does the motor turn over, have compression? Tune up. Looks like the fender ornament broke off, could of been a Greyhound dog or a number of other ornaments. I would not over clean, or strip anything. I don't see much bad here. Nice Whizzer. Do not disassemble, no need to. Do not sell off parts from it. He will love it. Best of luck, keep us posted.
