I have a rather nice vase table lamp which was given to me 10 years or so
ago. I have no idea where it originated from. Last night as I switched it on
there was a loud flash, some sparks and a noticeable absence of light
output. Stripping it down it appears that where the bulb plugs in is a brass
assembly holding a plastic fitting with two sprung loaded metal pins to
contact the bulb and the horizontal on/off switch plunger. One metal pin is
no longer sprung loaded so it looks like the spring underneath it broke or
melted.

Unscrewing the threaded brass rings which hold the lampshade holder and bulb
holder together I get to the aforementioned plastic bit into which the
electrical cable goes which is a sealed unit so no chance of getting inside
to fix it. On the underside is embossed "GM Série 100" so it looks like a
French manufacturer. It's also obviously an integral part of the whole brass
assembly which the bulb plugs into for this particular lamp and sized to fit
into the other bits. Other lamps I've checked have completely different
sizes and configurations of this bulb holder assembly bit so I can't just
swap out something from another lamp.

Google is no help in revealing who GM is other than apparently a large and
close to bankrupt car manufacturer.

Does anyone have any idea of where I might get a new part from or who GM is?

Can you take a picture of the bulb holder, as you might be able to replace
the whole thing.

Would any of these work?

Can you not get access to "inside" the lamp at all ..A pic would help
us if poss....Often the lampholders screw in to a small threded piece
which is secured inside and the flex goes through it and into the
lampholder . I thought when I read the above and saw

lampholder worked .:-)

Hmmmm, they might well. The thread that the lampholder screws onto measures
up at 3/8" but they also do a 3/8" to 1/2" adaptor so that seems to be
solved. Whether the lamp shade holder bit is a standard size I'm not yet
sure. Thank you for that link.

If you can get back to the point where you have the threaded 'post' on
top of the lamp then I have tons of the brass fittings that screw onto
this post (10mm) and are complete with the ceramic 'insert' with the
spring-loaded pins... - assuming that the lamp takes a standard bayonet
cap lamp...

Drop me a private email ) and I'll put one in
the post to you - might take a few days, what with Christmas & all
