Where is the best place to get instruction and parts for the featherweight? I went through several ebay postings before I settled on my FW. One ad ran the serial number that did not exist and when he corrected one letter in the number it still did not exist! The other machine I bid on was in the 50's but it looked real worn and tired. Finally...I think I made a good choice....I have settled on one that is a 1946 model and in great condition. However, it has no manual. I hope it is what they say and sews as well as they stated....will see when it arrives!
