BTR Diff Type Identification

[ukkid35]

Can anyone tell me whether this is a Hydratrak or not?

I've been told that it was originally from a Chim, but it had been bought from a dismantler

The rusty tag just gives a faded serial number, the 3.45 ratio and R0076

The new tag says 'CR - PM JS' is that from a rebuilder?
