Didn't the original generation Royal Commercial wide-track (18") metal uprights, although they had a 6.0 amp motor rating, use the 5.4 amp armature (1-618001-000) since the brush roll used in these (2-061821-000 or 2-161273-000) did not have the stiffeners?
This would apply to these models: 380, 618, 620, 680, 682, 7800 and 7820.
