The Singer 101 was the predecessor of the Singer 201-2 and the 15-91. It has been referred to as an experimental machine. The serial number is on the bottom of the machine on the right, near the hand wheel. It was Singer's first machine with the direct gear drive motor. It isn't as fast or as strong as the 201 or the 15-91. The bottom of the machine is fully enclosed, to get to the internals you'll have to remove 4 screws and the cover. Once the bottom cover is off, you will find a wick system and an oil reservoir. The oil was to be added through a hole in the machine bed then it would wick to the various oiling points. The wiring for the lamp is run internally through the pillar and arm then out to the light and is not easily replaced. It is a decent machine and a nice addition to a collection since it was the first gear driven machine. I'd pay 30.00 for it.

Thanks Mitch's mom for the information on the machine. The wealth of knowledge and sharing of information of the forum members always amazes me.
