Imperial Veteran Pins?

[Dave1104]

A friend dug up a coffee can from the garage that his father had given him. I'm trying to identify what I think are some Imperial Veteran pins. Can anyone give me some direction?

Thanks,
Dave

Here is a second pin from the same unit.

And final badge that is completely unknown to me.

Thanks for any help in identifying these.
