See what staying up 23hrs straight does to one's mind? I couldn't manage to loiter about any longer to take pics as its a 30min drive to the house, and I don't drive well while sleeping, unless they're REALLY short naps.
My 9C Savage has solid rivets, also. Oddly enough, due to the US Property marks, Savages are Bubba's favorite rifle around here, so that's my only good one.
Having bucked and squeezed a few rivets, I tend to pay more attention to them than most folk- that's my excuse anyways.
So Enfields, at least some Savages, and my mystery handguard have solids.
If you find some solids on yours -or tubular rivets on a Savage- please note the ID marks on the metal cap and on the wood (probably hidden underneath) and throw the info on here. Also, please note whether the wood in the cutout area was relieved for thr hinged forward band.
Cheap and quick "fun".
Pictures? You want steenkin' peectures? Well, OK, then:
Note the cutout in the wood.
Note- no cutout!
Remember Vultee, anyone?
The handguard riveting was MOST likely done in fixed tooling. However, Enfield seems to have done the trials rifle rivets by hand, no huge surprise given the cost of fabricating dedicated tooling.
BTW the rivets are AN450 tailed types but w/ flat or cheese heads as opposed to the usual AN671 heads.
