10 bucks--nice going! The 1205 "Jubilee" is a classic and was sold by "friendly Electrolux men" from 1974-75. Its honey-gold color denoted Electrolux USA's 50th Jubilee year (it began in 1924 as a subsidiary of AB Electrolux of Sweden).
In case you're interested in making a complete set, here's a list of the original tools and optional accessories:
1) combo rug/floor tool (ivory holder with honey-gold brush plate; metal swivel connector)
2) combo dusting brush/upholstery tool (ivory holder & "sides")
3) crevice tool (ivory, smooth texture)
4) white hose with teal/gold/teal tracers
5) Model PN-2 Rug Saver Power Nozzle with 50th Jubilee decal (ivory cord and wand sheath)
6) Shag Tool
7) White-bristled wall brush
8) White-bristled dusting brush
9) sprayer
10) vaporizer
11) Rug Washer (harvest gold top and base; ivory tank)
The Style C bags were the same for many of the tank cleaners from 1952-present, so they're readily available. Genuine are the best way to go, but some have said that the less-costly DVC brand is just as effective.
I wanted to mention, too, that the Model 1401 "Super J", which was made from 1975-79, looks very similar to yours, but has a larger motor and therefore a bit longer body to accommodate it, along with a "Super J" decal. Its tools and accessories were the same as those for the 1205 "Jubilee" except for its gold-colored hose and Model PN-4 Rug Saver Power Nozzle.

Happy E'luxing!
