Vapalux with a Bialaddin glass?

Just looking for some info if poss.
I just picked up this lamp, I think it's a Vapalux M320
and noticed it has a Bialaddin glass in it.
Is this the original or has this been added at sometime?
Many thanks in advance for your help

 

Hi , that shape glass first appeared on the bialaddin 315 model ,then the bialaddin 320 model which became the vapalux 320 when Aladdin industries ended their alliance with Willis and bates, hope this clears things up for you , if you look in the reference library at these models it should make it clear. The earlier 310 model had a much more rounded glass which wouldn't fit the later models.
Regards Ian.

 

What is written on the control knob?
Will give another hint at the lamp's origine.

Brilliant!
Many thanks Ian for that info.
So I think it is the original glass after all.

 

I just cleaned off the control knob and saw this..
I dint see it before
Cheers Matt

 

That's heavily eroded, not a single letter is legible.
So not sure if it's a late Bialaddin 320? The glass says yes.

@LatMag49

The thumbnail photo at the bottom of the last post by @Rhythmsync shows “Vapalux”.

@Tony Press Of course you are right. I've totally overseen the thumbnail.
So lamp and glass are mixed up
