ConD II* to .22 Short Rifle Mk III to .22 SR Mk IV* Barrel match ?

A spectacular collection of NZ .22's! I have a NZ Cond .22 though I restored it using MLE wood and MkI nosecap. Do any of these rifles have a NZ census/rack number on the top of the breech ring? all of my .22 have this as well as what used to be matched rack numbers on the bolt. possibly these new numbers were added when the rifles were converted to 'Trentham trainers' in the 60's
