Unusual phoenix glass for vapalux lamp

I got this glass with a vapalux lamp i bought. I haven't seen this logo before. Can anyone tell me more about it please??

 

In THIS post by @Tony Press featuring his Primus 1020 there was some discussion on the Phoenix brand globe and that its dimensions were very close to the Primus’s Jena Suprax product.

THIS Buflam also has a Phoenix globe.








... but carrying the Buflam name too.

 

Thanks for the info. Its interesting how sometimes lamps end up with unusual parts from elsewhere!!
