Aven Report post Posted December 18, 2020 I spent an hour looking for a manual or just more information. ISMACS didn't offer much, just that its an industrial machine it uses a 16X2 needle. I found one that initially appears to be in better shape than my 31-15 and I'm curious how the two machines compare. Does anyone have any information on the 31W?
