What age is this model machine? I am working out of town for the next couple of days, but have the absolute heaviest Pfaff made in the 60's, has original case and the extension table, bought it to sell, but have not advertised it and it also has lots of attachments and the original manual (which the front cover has turned brown from age). It sews very well, but I am amazed by the weight, made of total metal not plastic. Is this anything similiar to what you are asking about? When I returned home, if you will e-mail me, will be happy to attempt to help you with the extension table.
