I recently had a problem with the identification of various inch-pattern barrels in my parts collection. I consulted our resident New Zealand guru, Kevin Adams, and he came back with some good information. I've posted it here for general information.
Proof marking:
Crown
Crossed Flags
P
BRITISH L1A1 RIFLES
Have manufacture and part numbers on them, e.g.:
B59 960-2006
On the gas block:
960-2266
B 59
/|\ (broad arrow proof)
The maker and year can be differ. There are other proof and inspection marks.
CANADIAN C1 RIFLES
Have a minimal amount of markings on the RH barrel flat there will be the 4 point maple leaf proof mark (same as seen on the Canadian lower receiver).

There is NO shoulder on the barrel behind the gas block, like there is on the British and Australian L1A1 barrels.
INDIAN 1A1 RIFLES
Indian barrels have a serial number and part number on them e.g
BH5194 ICR 1232 (part No.)
The gas block foresight ears are short like a metric, but are open. The gas block has the part number on it.
ICR 1322
That's the whole story on how to tell one from the other.
