Sorry to revive an old thread, but i recently received one of these in a bulk lot, I'll have another look at it tonight, but its cowl by memory is in pretty good shape, the base is marked mayfair.
From what i can work out in the parts listing books, and from what i know of its history, i belevie it to be a 1978 Mayfaire Deluxe High Arch V190, I'll put a few pics up soon.
