Is it true that because the nozzle heads on almost any Royal metal upright (pre-1995, before drop-in motors) can be bolted between motors (given the right provisions between headlight styles), that sometimes I hear an older-style motor outfitted with a newer-style nozzle?
Flashback to when I was in elementary school (years 1988-1994). There were two Royal metal uprights: one had the standard-issue 14" wide nozzle (model 660Z) and the other an 18" wide-track nozzle (model 618Z or 680Z - likely 618Z due to the original blue bag on it that was later replaced with a gray zippered bag).
The 18" wide version sounded original, but the 660Z sounded rather '70s (think 3 amp motor sound, rather than the 6 amp sound). But during my 6th and final grade season (1993-94) the heads and bags were swapped: the 660Z now sounded stronger while the 618Z sounded weaker.
How many of you other Royal fanatics noticed a change in the motor's sound of one of these Royals, whether commercial or household, through the years, sounding either stronger or weaker?
