As always a few pictures are of great assistance in identifying the rifle. There's lots of CNo7 information in the "Knowledge Library" under "Canada
".
Having said that the earliest CNo7 (Canadian) is 1944 with the receiver marked { .22" LongBranch 1944 } stacked in 3 rows. The marking for 1945 are quite different and would ask that you confirm exactly what's stamped on the receiver. No serial number generally is an indication that the rifle was assembled by somebody other than the factory...Armorer, shooting club, private individual. There are CNo7 Ordnance receivers available...at least in Canada...that have been built into rifle as few were every released for sale.
You should also check the bolt for a serial number on the back face of the bolt. If 1945 it should be 1LXXXX and have "LB" stamped near the firing pin hole. If the rear handguard is removed you should see more markings. Internal parts and sights also will be marked. Have a closer look and let us know what you see.
Highly figured stocks are very desirable. Generally these were set aside for special builds. Not seen any unmarked ones on CNo7's.
Rare to see transit chest and cleaning tools intact.
I'd get a bit more information before purchasing.
