Bought a few tools today, including

and only when I got home, I saw that it was marked

Heinrich Böker (a.k.a. Henry Boker)
Online, I've only been able to find the double pelican mark with 'Henry Böker', as used in Australia, but none with 'Heinrich Böker'.
And I've only found date info for the Tree marks.

Any idea when this Heinrich pelican mark was used?

 

AI came up with this for me & cites "Nothing But Knives":

The "Double Pelican" or two-headed bird mark found on some vintage Boker knives is an authentic brand stamp used by H. Boker & Co. (Henry Boker). It is most common on pieces manufactured between 1920 and 1980, which were primarily produced in Remscheid, Germany, and often marketed in international regions like Africa and Australia. [1, 2, 3, 4]

Also, citing Boker, U.S.A:

While historically famous for its modern "Tree Brand" logo, Boker split into different family-operated companies in Germany during the 19th and 20th centuries. The Heinrich and Hermann Boker branch in Remscheid used several tool and bird logos, including the pelican. [1, 2]

All the usual caveats about AI.

They don't make it clear if that's the 'Heinrich Böker' or the 'Henry Böker' mark, but based on the addition of 'Germany', I assume that's the 'Henry' mark.

 

The Heinrich logo is shown on this site https://www.holzwerken.de/museum/hersteller/boeker.phtml, but they don't mention a date for that logo (they do for other marks )
"The emblem featuring the two pelicans comes from a plane owned by a Belgian museum. I was unable to find a corresponding trademark application. However, I heard from an Australian collector that the two pelicans are frequently found on knives and other tools made by Henry Boker."
