The photo below belongs to Wolfgang's Collectibles. This seller always has unusual and beautiful antique sewing machines, often complete sets. He currently has a listing for a complete Singer Model 20 Mannequin Set. (3 days left to the auction as of today) .
That listing ended at a price of $466.00 with 54 bids!!! Yikes! Bill Holman, with TreadleOn told me that his Singer Salesmen's Handbook from November of 1959 lists a Singer model 20-10 at $8.95 !
