Converted MkII* questions.

[Sapper740]

I'm considering purchasing this rifle but before I bid on it I need a little clarification on its stamps. On the left side of the butt socket is the expected Enfield 1907 SHt LE CONd II* (1V)? suggesting this is one of the 22,191 conversions done by Enfield in 1907. Everything is good so far. Take a look at the right side of the butt socket and this is where I get confused. The right side has an earlier stamp of Enfield 1896 SHt .22 III EFD under Queen Victoria's cyphre. According to books I've read the .22 Short Rifle Mk III wasn't introduced until 1912. Am I correct in assuming this rifle was originally an MLE built in 1896, converted to a SHt LE CONd II* in 1907, then into a .22 trainer in 1912 or later? But then there's another question: it has the Mark I rear handguard. I'm pretty serious about buying this rifle but the opening bid is spendy and I want to ensure that everything jibes with history. Please let me know what you think.
