Just a little rant: I had purchased two bolts, to see if one might be a thousandth longer and get my rifle to headspace.
The first bolt, advertised on eBay as "1917 Eddystone Enfield Complete Bolt" turned-out to be a P14 bolt; and the second bolt, from a GunBroker seller, arrived today in a parcel weighing a total of 4.5 ounces (including the box).
Arg!
