Very nice, and rare lamp!  Is the filament intact?  Thanks for sharing this.

Yes, the filament is intact.
This lamp has two supports in stead of three, as most pictures on the internet shows.
It also has a B22 Base.

I was curious about the date of manufacturing.
Has someone information about this type of light bulb?

I am really very happy with it.
It feels like to win a lottery (and I never won a lottery before)
I uploaded some photo's on the lighting-gallery, including some close-ups of the supports on top of the lightbulb and the stem.
The attachments are to big to upload them here.
Information about Osmium lamps is hard to find. I like to find out more about the construction and composition of the filament.
Also the marks on the base. 32/38/III  What does it mean? Voltage/luminous intensity/III or the opposite?
I am very curious about that.
