This lamp is iconic, representing the Art Deco period. A single peacock with a beautiful fluted shell like copper tail acts as a shade for a single bulb. This lamp is likely from the late 30s or early 40s.
Information about the company - Silverware Products (Canada) Ltd - is virtually non existent, but one source indicates it was operating in Toronto into the 1940s. It may have been a distributing company rather than a manufacturer.
Note that in pic two I have taken a pic with a 60 watt bulb turned on. Although it casts beautiful lights on the wall behind, I think a 40 watt bulb would be a better choice. The lamp measures 8 1/4" high and the copper tail is 8 3/4" wide. The socket (cardboard lined), switch, cord and plug are in excellent working condition.
As with any vintage electrical I offer for sale, I recommend that the item be taken to your electrician to have a complete check done before use.
The one main issue on this lamp is that the peacock body (non magnetic) appears to be brass plated and there are several areas of missing and stained plate. Check Pic 5. The bronze colored base is also non magnetic and very heavy. It has been lacquered and there are a few spots of lacquer missing. The copper tail also appears to have been lacquered and overall is in close to excellent used vintage condition.
