How about this for a "translation"?
On the end of the barrel:
"
C.A.I. ST ALB VT"
"
.303 UK"
Means imported by
Century International Arms St Albans Vermont, its the required post 1968 U.S. "import stamp". The caliber is still
.303 British.
I'm guessing whats on the "
left side of the bolt" is actually on the flat side of the reciever, not the actual bolt itself? Similar to the picture madecratebuilder posted.
Probably something like this: (replace the "
x" with other letters/numbers as needed.)
"
No4 MK2 ROF (F)"
Then probably a serial number issued by CAI during import. (the "
4/2134") as there are no No4MK2s I can find with numbers like that, most were either "
PF" or "
UF" followed by a year's last 2 digits, a space then a number starting with an "
A".
Like this:
"
UF 55. A189xx"
If I guessed right thats a Lee Enfield No4 MK2 rifle made at the Fazakerly (Birmingham) factory in the 4th month of some year between 1949 & 1955 when production ceased. Some had dark, or dark stained light wood, some were left blonde (with light colored wood).
Heres mine with the light wood:
There should be numbers elswhere as well. on the back flat of the bolt handle, on the bottom of the magazine & under the wood at the front end, halfway between the end cap & the middle band. If the numbers are the same its a "matching" rifle, having all its original components, if not you should get it checked for headspace before firing it. I cant help with the numbers on the wood, they're probably "rack numbers" telling where the rifle was to be returned for storage after use.
