If you haven't already, go over to Yahoo groups and join the VintageSinger group and the SingerSlant group. Both groups have lots of files and info. I have a Rocketeer - a 500 - and what a call the Rocketeer Jr - the 503.

Getting that top plate shouldn't be too hard...usually you can get them for 20.00 if you look long and hard. Great machine and surely a classic every singer collector must have....
