Thanks, Doug!
Now, calling all IEC Compact Pundits in a quest identifying and dating the ABC Power Nozzle...someone won this on eBay in January 2009. Bidding was fierce iirc. Was it one of us? Come out, come out, whoever you are...
If the IEC Compact chart is more or less correct, and I have no reason to think it is wildly inaccurate, Compacts can be generally dated by the Model No consistently cast into the bottom of the magnesium shell. More precise dating comes from the decorative graphic Anniversary Decal often applied to the opposite side of the vacuum from the chromed 'Compact' script. The yearly count begins in 1937 with the founding of IEC - Interstate Engineering Corporation - although the first vacuum sold to the public, The C-1, came out in 1946. Compacts were and are sold only door-to-door by Salesmen to the present day, as the Tristar.
Thus:
C-1 - 1946-48
C-2 - 1949-54 - 25th Anniversary 1952
C-3 Revelation - 1949- 54 - sold only in retail stores
C-4 - 1955-58
C-5 - 1959-60
C-6 - 1961-70 - early ones have a single front ball caster, two thereafter.
C-7 - 1971-72 - now called the Compact Electra (?) But then so many early logos have broken off and been replaced.
C-8 - 1972-78
No model designation but known in the hobby as the
C-9 - 1982-85 - sometimes labeled TriStar.
The name changes to TriStar with the 1986 50th Anniversary Model CXL
What follows is speculation based on 11 Compacts in my collection and files. I'm sure it is rife with mistakes. Please correct or confirm these guesses. Compacts are such robust long-lasting vacuums that they are refurbished regularly and re-sold.
Although we know the ABC Power Nozzle was/is a fact - and has a decidedly late 1950s aura - it is likely it was meant to be plugged into a wall socket. The dedicated two-pin power socket below the latch does not seem to appear on the Compact until the C-8 in 1972. There are pictures of an earlier Compact with a PN socket but it is mounted well back by the handle strap and exhaust grill, which is also the cutout location for the switch on the two-speed model.
Pictures of the ABC wand socket clearly show a two-pin socket mount in the back and so I speculate that the ABC would be supplied with a long two-pin cord with either a two-pin plug to insert in the vacuum body, or a two-blade plug on a longer cord to reach a wall socket, as required.
Whatcha'll think?
