The 6-qt may also interchange with White Mountain 6-qt freezers. The 6-qt Stainless Steel can measure 6-1/8" x 12" high and will fit most older model WM freezers with a 7/16" bottom can peg drive made from the late 70s and forward. Some of the early WM models used a different 3/8" peg drive inside the bottom of the can. This can will not interchange with those older models. You can verify using a 7/16" open-end box wrench at the end to see if it fits over your current bottom can peg.
The 4-qt can measure 6-1/8" x 9" tall. The 8-qt can measure 7" x 13 1/4" tall. These will only fit the 4-qt and 8-qt Immergood freezers.
