Help ID Berlin tinnies!

[vellocino]

Hi, I mostly collect German Imperial photoalbums, and I don't know if these are classified as tinnies, I could not find information or any other similar example to these two "tinnies" found in a German WWII period photoalbum, and I really need your help to ID, determine if they are real and the rarity/value of these pieces.
I really appreciate your time and kind opinion about it.
One is related to the Berlin Tempelhof Airport and the other to the Berlin Reichssportfeld.
Any info or lead will be greatly appreciated.
Thank you,
Velllocino

Dependant on size, but maybe these were to attach , by bending, to walking sticks?

I feel Jon has hit the nail on the head (pun intended)

Thank you for your input. Are they of interest to some area of collecting?
Not my area of collect, but wondering if they are of interest for someone on the forum.
Thanks both again for your answers.
