I tend to collect (hoard) everything i can get my hands on - wood, barrels, sights, bolt heads, bands, screws, whatever - you name it. Fortunately 90% comes to me very cheaply thru older associates of my father. Eventually the parts are used for turning sporters back to orig mil configuration, and/or bringing beat up old warhorses back to shootable life (I'm a shooter of, not collector of Enfields i guess you could say) Some parts may sit in back of cupboard for years before use, some not so long. I'm also often able to use my supply of parts to do trades with my local enfield loving shooting associates - parts they need for parts that i need type arrangement - helps us all keep costs down. Here in OZ the price of parts (as with decent Enfield Riflesicon) can sometimes be ridiculous $
