i have a i have a 1941 lithgow SMLE. the roman numerial stampedon the action is either a 2 or 3 but it is worn and hard to make out. my dad bought this at a hardware store for $19.00 when he was 18. that was in 1959. i have seen tons of .303s that look the exact same as mine and have probably been converted by the same firm. this is a great shooter as my dad only used it a handful of times before he left it at the farm and forgot about it. he thinks the sporter job was done by parker & hale. the letters BA are stamped on many parts such as the bolt and safety switch. does any one have any info regarding these common rifles.
