[QUOTE=Nollsgame;7119136]Has anyone heard of a Shapleigh Model B? Can you help determine the year?
Shapleigh was a famous hardware store chain based in St Louis and this rotary sewing machine was made by National for them. There's a Yahoo National group which might have some dating info based on SN#:

Has a 1920's or 30's look to me.
