Hi John, and welcome.
The bad news is that your hull number is gone with the piece cut from in front of the driver. Any chance of tracking down the cut out piece?
Regarding the holes at the right rear (Aerial mount) Nigel Ward made them. there is a long thread about them if you do a search.
I see the division plate Bren mount (pintle mount) bracket laying on your inner guard (track guard)
She looks like she is in great condition. It would be great to be able to start from there.
Don't be scared to ask questions, and keep the photos coming.
