I'm not a Pfaff mechanic either, but have worked on my own and will continue to learn. I have a Pfaff 1222 also. The embroidery attachment looks like it would be a blast besides I love how it and the added lamp make the machine look. It goes from a tough looking machine to semi-industrial looking. Very cool! I'm not sure if the attachment can be just added on to a 130-6 or whether it had to be factory installed? It looks like the back piece comes under and attaches to the front knob. That thing wouldn't be waiting in storage here lol! Aren't you dying to play with it? :p
