I'd have to go look at some and maybe do some more research. But, I think you are right that the surplus ones are the LV. I believe that the differences between the N20-LV and N20-HV are not as great as the differences between the M20-LV and M20-HV. In other words, relative to their size, I think the M20-LV is a hotter wind motor compared to the M20-HV. I think the N20-HV is pretty much available from sources like DJ Aerotech and Kenway. The ones Todd sells are the LV. I've bought them from him and from All Electronics. I haven't bought the N20-LV from other sources than those two. The GWS may not be a genuine N20. There seem to be a number of companies that make N20 clones.

The geared versus DD issue is probably why Matt tested the motors and props for his P38 in a wind tunnel, to get more realistic measures.
