Yeah its a 2a... Should have the large serial digits the same as the model 2 roto. Earliest one ive ever come across. Cowl and pulley are getting hard to come by and may at a min cost you 150 pulley and 180 cowl up to 200 and 300 approx,so be patient and wait for the cheapest you can get. Ive seen some go for less especially when a few come up at once....So keep your eyes open:) Unrestored completes are now selling for upwards of 700, so its a fair investment as they are nearly as rare as the model 1 due to its low volume (even less than that of the auto) although much cheaper in value. Good luck they are a prized model and very desirable:)
