Wider no rilled lip 1960’s- 1969:
Both the slimline and wider rolled lip versions bakerlite shades occasionally turn up. These are pretty rare as the bakelite shades were brittle so few survive. I believe the reason bakerlite was sometimes used (though this may be wrong) was that in the run up to and shortly after the second world war, there were often shortages of various materials including aluminium.
During these shortages it was not always possible or affordable for the shades to me made out of aluminium so Terry and Sons would resort, for short periods, to producing shades from easily moulded bakelite. This was however problematic as they were very brittle and often had faults form during the manufacturing process. The shades also often cracked or shattered during delivery, so as soon as aluminium was once again available they would return to using the more reliable metal.
First version seen on 3 step base’s:
Centre: Early 2 step models from 1938-mid1940’s
Left: seen on models from 1952- late 1960’s
Right: This is most commonly seen on the Anglepoise Type 75 which replaced the 1227 in 1969. However it is also seen on very very late 1227’s (presumably the crossover period for manufacture).
Base’s: 3 step (1935-1938):
Genuine originals were painted, usually with wrinkle paint, with uneven castings. Very early examples may have no earth screw and may be stamped ” The Anglepoise Pats Pending’ rather than later examples which simply state “Patented”
Early 2 step (1938-mid1940’s):
Note: no steel cover just lumpy casting, wrinkle paint was used to hide this
Later 2 step (1952-1969):
This is the same as above apart from that it has a pressed steel cover over the cast base, this was brought in when gloss paint began to be used on the lamps to hide the uneven casing.
