Where can I get a belt for Magic Chef 250-2 model breadmaker?

None of the breadmaker parts suppliers seem to be able to match this model....made in China. It was a gift so I don't know where it was purchased.
The drive belt is flat. I measured around the drive pulley and the paddle wheel with a string and it was 25 inches. The pulleys have 3/8 inch wide, flat groove. The drive pulley is multi grooved, like a timing belt drive.
