    Its likely a 3650 series motor based on those dimensions. Does is have a black or gold front endbell? That will tell you if its a newer V1 (gold) or older V2 (black, yes, their naming scheme is backwards). As for the numbers printed on it, might be a question best asked of TP directly in an email.

    It’s a black end bell , So can you speculate on the KV ? Thanks

    Nope, but I can tell that you have an older model 3650 based on that info. If you look into the rear end cap and count the number of wires bundled together, you can determine Y vs D wind, which would again limit some of the potential kV options. I'd fire an email off to TP with the numbers on the sticker to see if they can identify it, or, get yourself an RC airplane RPM tachometer and measure the kV yourself.
