HEER Pith helmet shields.-OK?

[TP Alexander]

There are four of them.
The left two are unmarked, the top right is marked 'R.K.' and the bottom right is an Assmann.
Thoughts on authenticity?
Just want to make sure they are good.
Thanx,

Not quite sure is the upper left eagle's pebbling inverted ? Little hard to tell from the photos. The other three are all nice original eagle shields.

looks like you have 4 good ones

4 nice pith helmet eagles for me. The 2 bottom ones look like Assmann even though the tombac one at left isnt marked
