Pryanco AMPCO presumed to be manufactured by Pryanco
This Chime marked AMPGO is presumed to be manufactured by Pryanco because of its resemblance to their other cast cover chimes. The original mechanism is identical to other two note Pryanco chimes. Perhaps AMPGO was a private label or merely some code in the mold. This cover is not shown in any known Pryanco Catalogs or ads.
When the first example was sent to the Museum, all that remained was a fabulous art deco stye cover under several layers of latex wall paint.
The Museum built a new mechanism and manufactured two new bells to factory specification. The cover was resprayed in the original bronze color. The black grill cloth is a modern addition. The second example from a San Francisco home retained its original finish, silk grill cloth and mechanism.
Pryanco was a large supplier of door chimes in the Western United States before being absorbed by Rittenhouse in the 1950s.
Please contact the doorbell museum if you have further information about this chime.
