30-06 dummy

I just got this in the post and I was wondering if someone could tell me something about it.

It’s a 30-06 case, headstamped ‘LC 42’ with four rather nicely countersunk holes drilled through it. The bullet, which is non-magnetic has been soldered into the case.

In anticipation, Peter

The Netherlands made dummies up from surplus fired cases in the way that your dummy has been made.
