Firstly, are you sure its a No1 MkIII?
A good way to indicate this, is the location of the rear sight. If it is on the barrel ahead of the chamber, its a No1 MkIII. If its behind the bollt handle, its a No4 Mk1/Mk1*.
Please indicate any makers marks, located on the right hand side of the rifle, under the bolt.
RFI No1 MkIII's are 1943 and beyond. I had an old RFI 42 in Canada. Also so are Lithgows, so could be Aussie also. I have two Lithgows, a 1916, and a 1942. Lithgow No1 MkIIIs were made into the 1950s. Lithgows 1940s are marked MA on the receivers.
For No1 MkIII, you will need to ensure the fol:
- barrel is original length, uncut and has original front sight (if its altered you cannot restore it).
- rear sight is original
- bolt matches to serial on rifle, if not IMHO its not worth converting. This also goes if the reciever has been drilled and tapped for a scope. Often the magazine charger is removed for this purpose.
Now, if memory serves me right, you will need a set of wood (complete). This consists of the fol:
butt stock w/ butt plate screws and rear sling swivel w/bracket and 2 screws
forestock
forestock upper, front
forestock rear
rear sight protectors w/ screw
nose cap w/screw detent and spring, and side retaining screw
front sling swivel band w/ swivel and screw
Make sure you take off the stock before the other wood. If not you will destroy the forestock.
You can take some pics and post them here if you are uncertain.
If you live in a city, they have gunshows, you can buy all of this stuff you need to convert. Speak to a dealer at a table, and tell him your delema, and he will have it all. I would say you should be prepared to spend $80-$100 for what you need.
No4 Mk1's require a reciever ring to hold the top rear foreend on, and its a bit more complicated, as the front sight ears have to be removed, and this ring slid on. Finding one might not be as easy either.
Waiting to hear back from you.
Good luck.
Let us know how you go.
