Class 66 Survey Results
There are six Model 66s in the survey, ranging from 1910 to 1948, 5 treadles and one electric in a cabinet with both knee and foot pedals.
The 66 has a round, top loading bobbin. During bobbin winding the thread goes through a cleat or tension discs, or nothing, on the bottom right side of the machine.
Five of the machines have spoked balance wheels with chrome edges and the 1948 machine had a solid black balance wheel. All have shiny black finishes and the faceplates are not flat on any of the machines. All have round plates on the back, right side. Both plates had the same design which fit into the following categories:
3 had floral/leaf designs, 2 had oval/leaf designs, and the 1948 is lined. The stitch length adjuster is an unmarked knob on four machines, a flat lever in a numbered slot on the 1948, and not described on one machine. There is no reverse or zigzag stitch.
The upper thread tension is unmarked in front on five of the machines, and numbered in front on the 1948. The decals are described as red, green and gold and/or heavy floral for the first four machines and delicate floral for the 1926 and 1948.
All machines have the large 1-5/8" Singer medallion. The head measures 14.25" from faceplate to far end of the balance wheel. The bed measures 14.5" x 7".
The 66 is a straight needle machine. Four surveys described the 66 as a low shank and two surveys called it high shank. The 66 had no light until 1948, & that had a light in the back.
The first 5 machines are treadles, the 1948 is electric, in a cabinet with knee lever and foot pedal.

Class 99 Survey Results
The are six Model 99 machines in the survey, ranging from 1923 through 1955. Five electrics with a foot pedal and one hand crank. All have a round, top loading bobbin. During bobbin winding the thread goes through a cleat on the bottom right side (3), tension discs (1), other (1), and not described (1).
The balance wheel is spoked with chrome edge (1), solid with chrome edge (1), and solid and black (4). All machines have a shiny black finish.
Five surveys reported flat face plates and 1 reported a not flat face plate. Face plate designs varied, 1 floral/leaves, 2 lined, and 3 other. The earlier 5 machines have an unmarked knob for stitch length adjustment but the 1955 has a flat lever in a numbered slot.
The 99 has no reverse or zigzag stitch, (although the later ones appear to have reverse stitch). Most surveys reported delicate floral designs as a decal description.
Four surveys reported large 1-5/8" Singer medallions (including 1 Anniversary and 1 Centennial); two surveys reported small,[1-1/4" Singer medallions.
The head measures 11.75", from faceplate to far end of the balance wheel. The bed size is 12" x 6.5". The 99 is a straight needle, low shank machine. Five of the machines had lights mounted in the back, one had no light; three are portables in bentwood cases and three are electric, mounted in cabinets with foot pedals.
