German WHITE
Do not find mention of this model in the places WHITE information is available so if anyone can identify it please do so. If there is a manual for it or close to it please point the way to it. Any information will be welcomed. I'm thinking about using it in a treadle but need to do a bit more study before doing that.

Needs a straight stitch needle plate for serious treadle use. The covered gear boxes must be free of heavy grease and a way to access the bobbin freely from below must be considered.

The discs on the left side are - two thread tension adjustments. The large disc centered under the two thread tension discs is the small tension spring that works with the tension system. No tension in this part but it is also the needle position-er. The drop down lever is the zig zag selector. On the right side find the stitch length selector (the top round one)and the two long vertical slides - on the right side is the feed dog up and down, on the left side is the forward - reverse.

Close up of the two thread tension discs at top. The bright metal on is the needle position-er and the small thread take up spring that works with the tension system discs (in view toward back side on the left side). The dark lever to the right side selects the zig zag stitch.

The top knob sets the stitch length (will make 5.75 stitches per inch). The slider on the right side in to position the feed dogs. On the left side is the forward and back tack plus works with the stitch length knob above it.

Back side view. Notice the WHITE plug on bottom side of motor. This machine has two different sets of hinge pin mounting holes along the back edge. One set of holes are the same as used in Singers and clones.

You notice the fine German enginering through out. Notice the covered gear boxes in the two usual places one under the hook and race and the other at the down drop in the post.

Interesting that the motor is mounted (ridge mount) to the rear side of the post. There is a motor boss under the hand wheel unused. This mounting lacks a way to adjust the belt tension.

High shank presser feet and 15X1 needles.

The bobbin faces forward and this very tight area is just not enough for my hand to set a fresh bobbin. This could be an issue in setting this fine machine in a treadle.

The rotary hook system is held in place by the 'finger' at the top. The bobbins are the same one used in the Singer 206. This bobbin is also used in many rotary machines both domestic and industrial.

Well made controller runs hot but is away from the foot peddle.

If used in a treadle the gear grease would need to be changed to a very light grease such as Tri Flo and only a small amount used to reduce as much resistance as possible.

Same in this gear box. This would be a very fine machine in a treadle if access to the bobbin is provided and the resistance in reduced such as would be present using heavy grease.

The only damage seen so far is this oil port that was removed. This view is from the rear side and is of the top of arm near the needle end. The two tension discs are in the view barely.
