Unknown suspension identification

[floriskok]

Hello guys,

I found this pair of suspension in a lot with only IF8 Infanteriekarren parts and
I have no clue what these suspension parts are from.

They are smaller than IF8 suspension and I was thinking some kind of motorcycle
but I can't find anything similar.

Perhaps you know what these are from?

Thanks in advance for your help!
