Frames In-progress

It has been reported that there are actually 11 different frames. We've only found 8 so far. We need your research to help us find the missing frames - or to clarify what we've written so far.

Year Frame
Frame #1
Early 1948
Model 125
Part# 47002-47 - Characteristics are the plate for the kickstand mount, and coil bracket hanging from the upper horizontal tube. The fork neck was just a piece of tubing welded to the frame downtubes. This was a poor design and broke easily.
Frame #2
Late-48 - 1950
Model 125
A running change was made during 1948 to correct the breakage problem. The fork neck was a cast assembly which had "stubs" - the front and horizontal tubes were inserted into the stubs, and the assembly was "furnace brazed" together. Believed to have changed in mid-1948 production.
Frame #3
1951-1952
Model 125
The 1948-1950 kickstand was also a poor design. The bolt holding the kickstand to the frame would loosen, and the tangs in the kickstand would break off. For 1951, the kickstand was moved from the frame to the left footrest shaft. Hence, the kickstand mount was removed from the frame.
Frame #4
1953-1959
Model 165
Part# 47002-47A - The new 165 engine design necessitated moving the coil from its old position above the engine to a new position in front of the engine. Hence the coil mount was removed from top horizontal frame tube. Instead, bosses with holes were placed in the front downtube.
Frame #5
1955-1957
Hummer
Part# 47002-55 - The new Hummer engine used a coil inside the magento for spark, so no external coil was needed, and the bosses for the coil mount were removed from the frame. The Hummer's squeeze bulb horn was mounted on the front fork, so the mounting tab for the electric horn was removed. The toolbox was an option on the Hummer, so the toolbox mounting tab was removed from the frame. The footrest tube and footrest shaft are a single assembly.
Frame #6
1958-1959
Hummer
Part# 47002-55A - The Hummer magneto's internal spark coil was a bad idea, so an external spark coil was used. This necessitated the return of the coil mounting bosses and holes in the front downtube.
Frame #7
1960-1962
Super 10, Pacer, Scat, Ranger
MORE RESEARCH NEEDED HERE! The 1960-1961 Super 10, Pacer and Scat. The electric horn was moved from the frame to the front fork (behind the fork panel). As with the Hummer, the toolbox was an option.
THE PICTURE - Part #47002-47B from the 1960 Parts Book picture which says "Fits 48-59 S, ST; 55-59 Hummer, and 1960 Super-10.
THEORY: The Hummer frame was used on new bikes, and this one is a fits-all replacement part???
Frame #8
1963-1966
Pacer, Scat, Bobcat
Part# 47000-63 - Rear swing-arm suspension
