G'Day Ridolpho,
Well, she's done the rounds, hey?
Built in the UK, issued to the Queensland Police, quite possibly not all that long after manufacture. Rack number 594. Some years as a QP rifle, then handed to the Australian
Army, hence the D Crowsfoot D symbol on butt. There's a fellow on another site that seems to know a bit about QLD Police numbers, he must have access to records of rifle nos.
The Australian Army relegated the rifle to Drill Purpose as noted, then struck the delegation out prior to selling out of service to civilian property, noted by the opposing arrows on the Nocks Form (knox if you wish).
Thinking about Jim's likely comment, I haven't seen many sold out of service arrows on pre-WW2 surplus sales, but that doesn't mean they aren't around, just not ones I've come across.
An managed to travel then to Canada. Not a bad service life, hey? Treat the old lady well, she deserves it.
