There are always plenty of people wanting to buy a decent Model A wheel, whether it be 21" or 19". 21" are by far the most common here but I am aware that prices over there are cheap compared to what we have to pay. Your wheels will find a home if they:
- run true
- no cracks in the centres
- no or minimal bent spokes
- bolt holes not flogged out
The more of those problems and the worse they are, the less desirable they will be, IMO
