You can really appreciate its simplicity when it comes time to lubricate it and not have to worry about the mechanisms used to drive cams, zig-zag hardware, needle centering, etc. Additionally, it is much easier for the motor. There is very little which can go wrong with the all-mechanical 185 if it is kept cleaned and lubricated. The electrical cords should be checked often for signs of deterioration or wear.
We read from a posting by Bill Holman that the 185 sold from 1959 through 1962, and with the green plastic case it cost $119.50.
There should be a glass lens in front of the bulb. You push in slightly and turn it to release it. You won't be able to find any of the original round bulbs if that is what it still has, but a 15w with the same screw in base will work.
Features we like:
Smooth, quiet and well balanced
Easy starting-you don't have to manually spin the handwheel
Good range of control on speed from slow to fast using foot control.
