SBP 14x5.5 Rim

I have one but all that I can find is a "K" and a 3 stamped by the valve stem. It does have a label on the inside with KH-82236 printed on it so I'm guessing that it's a replacement rim and not a factory installed piece.

I already have a fourth rim that is not matching but I do appreciate your reply. Thank you!
