Panzerjäger mystery - solved!

Panzerjäger UE in all it's glory!

Deephorse of TMP has supplied a link that identifies this little vehicle as an example of the catchily named:  "3,7cm PaK 35/6 auf Infanterie Schlepper UE(f)"  In other words a 37mm PaK slapped on top of a French UE carrier.

If the link is followed you can see the newsreel shot developed as a still and it is much clearer.

Thanks for sorting that out!
