Help identifying this Whizzer

[CharliePatt]

I’m helping a friend doing some rehab on this bike. Any help in identifying its details and comments regarding originality and such would be appreciated. He believes it’s a 1947 but from my research some things don’t seem to agree. The frame is a Schwann SN E009938. The engine SN is 250481 with no H or J prefix. See pics. Thanks

Can anyone help identify the engine? SN 250481 with no letters in the number.

Maybe @Goldenrod can shed some light on the motor.

I spoke with @Goldenrod about a similar engine number and he said that if the number is below 300,000 then it is an H engine.

There is a poor stamp of a J before the #. so someone forgot it and tried to fix it. The rest is set up as a J. Big package in a few days.

Are you referring to the impression at the 2 o’clock position above the bolt? I’m not understanding what you meant “the rest is set up as a J”?

BTW, the bike has been completely repainted (Restored) It's an OK paint job but, not professional as whoever pin striped it, hands are a little shaky. So, your engine and other parts may not match the date on the frame.

I’d say yes the U shape above the bolt was most likely a J. Just not struck correctly. The rest set up as J. I’d gather he means it’s accompanying equipment is indicative of a J model Whizzer set up.

I think the trim color may have been white and someone painted over it with the black with red pin stripe

And is a J conducive with a 1949 model frame so that it would have been factory?
