Anyone Recognize these Spider Sights?

Or rather...one Spider Sight and one Sight Post...

These came to me with some other German items...but I think they could be American? No marks or stamps...plus the orange rubber is strange.

Maybe for a 20mm Oerlikon or Gun Camera?

Mounting posts are the same...so I am assuming they are a matching set.

Thoughts?

They are for the ‘46-50 Madsen LMG. Missing are the mounting bracket and hardware and the leather carry case. Fairly common in the US and really not applicable to any other MG.
