Looks like a good candidate to restore.
Serial number and markings are elecrtro penciled on not stamped so this was done later (FTR), I suspect that its not a 2 groove barrel but thats hard to say.
Looks like some of the markings were removed when it was sporterized. Its a Mk1 not Mk1*, I need to look at my reference books.
But what I'm thinking is its an earlier rifle (Mk1) but its marked with electro pencil, which would be later, but no makrings indicating a FTR, perhaps removed. Serial number appears lower on the wrist then normal stampings (AA33????) perhaps all the earlier markings were scrubbed, or the rifle was rebuilt on an older reciever.
look for a date on the left side of the barrel knox just above the woodline, should be a 2 digit number like '47
edit
another thing just struck me (ouch) The markings appear to have been blued over, perhaps another sign that some of the markings were scrubbed off the reciever and the reciever reblued.
Still this is an excelent candidate for restoration, some wood and a few barrle bands and your almost done.
