I have been able to confirm a couple more cabinets that were brought to my attention by
@Bass 45, so here's an updated list.
Vintage, period-appropriate cabs:
V4B - a folded horn 2x15. 48"H x 26.5"W x 24"D
V6B - a direct-radiating, ported 2x15. 41"H x 27"W x 15"D
B25B - a direct-radiating, ported 2x15. 40"H x 29"W x 12"D
B40 - a direct-radiating, sealed 4x10. 30"H x 27"W x 14"D
Cabs that were made after the original V4B head was discontinued, early SLM-era cabs without white piping:
SVT-18E (not the SVT-18) - a direct-radiating, ported 1x18. 24”H x 27”W x 16”D
SVT-410E - a sealed 4x10 (no horn like the later 410HE has). 24”H x 27”W x 16”D
SVT-1510E - a direct-radiating, ported 1x15 with a sealed 1x10
27" wide, height and depth unknown at this time
Cabs made after the orginal V4B head was discontinued, SLM-era cabs with white piping:
V4B (V4BH-era) - a folded horn 2x15. 48"H x 26.5"W x24"D
SVT-412HE - a direct-radiating, sealed 4x12. 29.25"H x 27.5"W x 18.25"D
There may be some MTI-era cabs. Maybe the same ones as the three early no-piping SLM-era cabs listed above. I have not found an example to verify. Here's a pic of an SVT-410E. Waiting on info about era.
