I have to dig out my Enfield books again, thanks Rob.No Primers:
Google Springfield Sporters. They have 100,000+ parts for Enfields. Call them Monday and ask for Long Branch parts,they should have them. I get most of my British firearm parts from Springfield,have been for 30 years.
Edit add on---- All of my Enfields,No1 Mk3,No4 Mk1,and P14 have the offset sling swivels. I think that is correct for all models.
