Who is the maker of this motobike and would anyone happen to have a badge?

Westfield motos had similar construct to your bike....with the lug at the seatpost/dblbar junction. Below is a Columbia by Westfield...Westfield seems to have been keen on the top bar bend near the middle of the span...with the noticeably smaller diameter lower bar below. Many frame variations from them...straight seatstay bridges were another clue that points to Westfield..

Thanks for the rubbings (-:

I still can't tell much, though. I'm sorry about that.

If the bicycle is a Westfield, then the number cannot start with a 0. It would need to start with a letter (also not followed by 0). The letter O was not used, so perhaps it's the letter D?

Unless it's upside down.

Why do I keep saying that? Because the vast majority (maybe all?) of Westfields have the number stamped so you can read it if you are facing the bb from the downtube end, which is opposite way up to the photo. you have.

I wish I could give you a better answer.

Best Regards,

Adrian

Maybe an H-28,390 from 1930?

I use a piece of sandpaper, rub paint off across the numers then they will show better.

Maybe an H-28,390 from 1930?

Or "I" 28390?

I thought that Westfield skipped “i” and then proceeded to 1931–J.

What bike did you ride today? | General Discussion About Old Bicycles

Rode the 1930-H Westfield Hawthorne past the Russian churchoff. Working on the left pedal shaft-spindle; got it to rotate back and forth to a degree; (wondering if I have an interference-fit RH pedal in the LH hole).

But in 1930 it seems, Westfield transitioned to a frame with slightly different details.

What you need to do is look at SHELBY bicycles... which is what your sprocket, fork and frame appear to be.

It appears to be an "S-M-B" (SHelby-made bicycle).
