Siemens & Halske Wotan 60W 110V Incandescent lamp with tungsten filament
Siemens & Halske Tantal 60W 110V Incandescent lamp with tantalum filament

I don't know how old these lamps actually are. Siemens & Halske stopped the production of tantalum lamps 1914 but this lamp has a Mitchell and White exhaust that was introduced in 1919. I contacted the Siemens Historical Institute because they show this lamp on their website. Unfortunately they can't answer my question at the moment because they are doing home office because of the Corona virius.

My theory is that they were produced as memorabilia around 1920 shortly before Siemens handed over all production facilities to Osram.

These are relatively modern, and were produced for a special commemorative event. I have seen a write-up on them somewhere in the old Osram literature, and am struggling to remember now if they were made in 1979 for the Edison Centenary, or possibly for the 50th or 75th Osram brand anniversary. I will try to find out and come back to you! You can see that they are modern due to the use of a normal exhaust tube within the glass stem - the tip on the bulb crown is only for decoration. The stem press is also reminiscent of 1970s/80s Osram projection incandescent lamps.

That would be very nice if you could send me a scan of that article when you find it!
Do you know where they were produced? Maybe in the Osram Lab? I guess the production run was fairly small and didn't justify the use of the production line?

I'm looking for:
Osram L20W/39
Osram HTI 1500W/60/P50
