I found this machine for sale locally. The only info they have is it's a Consew with reverse. And it's the head only. I asked if they could find a model number and they responded back no but they think it's a 226 because it has reverse. Asking $500. I was wondering if anyone could tell me what model this is for sure from this picture (the only one they posted) and if it's worth this price or what this would usually go for. Also if it's the head only, what else would I need to get for it?
