Bialaddin 306, very rare

I'm looking for information about this rare model. 300 or 500cp?? Does anyone know the differences with the 305?
Cheers

 

@Cesar

Can you provide a clearer photograph of the number “306”?

There is no reference to Bialaddin 306 in the @Mackburner Pressure Lamp Catalogue.

I think the collar is stamped "300". Perhaps a typing error? I do that all the time when I'm typing.

 

Yes it's a 300. The only difference I have found between 300 and 305 is the 300 globe cage rods are riveted in place and the 305s are threaded with upper and lower nuts. Vapalux are always rated at 300cp. I am not aware they ever made any other size. ::Neil::
