Coaster brake hubs where?

Hi, first time, posting here, and I would like some advice if poss.

I am looking for Rear a Single speed coaster brake hub for a frame
with 110mm spacing between the drop outs. Ive the local retailers,
council tip, and searching the web without much success.
Just wondering if any one in this group might know of a likely source
of one of these hubs???

Thanks Markb
