BIG project & a lot of work, good luck, don't waste your time building a dust cover, will take days & I think $75 should buy you one ?

Oh & no one sends firearm related items to NZ from the US any more from my experience at least not many, most will not even reply (there's another country out side the US ?) I've been building & rebuilding BSA Sporters/Lee Speeds for over 15yrs & still haven't finished many of them !

If you get time post some photos .
