I was at a gun show today and had my eyes out for a nice lee enfield. I came across this one and decided why not and bought it for $450. Not knowing a great deal on lee enfields I would like to know if this is a good one? It says "ShtLE V 1924" near trigger guard and came with what looks like a period correct sling. All the serial numbers seem to all match (bolt, reciever, stock, bayonet lug) and looks like it might be missing a front band and the circular piece of brass on the stock. The bore is in good condition. I did a little research and found out it might be a SMLE mk 5? From what I read it said there was only around 20000 produced as a trial rifle? Any info you guys could provide would be greatly appreciated. Thank you!
