Identifying these suckers
Let me see if I can identify the rifles in Rowdy's post, according to the BSA Catalog circa 1912, pages 14-16, reprinted by Skennerton in "B.S.A. Rifles and Sights" (but not, unfortunately, in the new "Lee Enfield" book. I guess running a full page ad for the AIA hybrid was deemed more useful than giving more attention to the classic sporters. Sorry for the dig! Couldn't resist.)
First pic (BSAriflesNo1and2 J.jpg): The No. 1 Pattern is on top. It has the barrel rib. Is there a BSA safety of the buttstock? I don't see one, but since there's no safety on the cocking piece, I assume there must be one. The No. 2 Pattern is on bottom. This differs from the catalog only in having a 5 rd mag, but these were of course customer options. The BSA buttstock sliding safety is evident in the photo.
Second pic (BSAriflecarbine.jpg): The one on top must be what BSA calls the No. 4 Sporting Carbine. Has military wood (though checkered). Catalog shows checkering available only on buttstock, but perhaps fore-end was an option later. The front sight differs from the catalog. Interesting that it retains the gunmetal buttplate. Now this one you say has an SMLE barrel rather than a cut-down Long Tom barrel? It doesn't look thinner, but that's hard to see in the photo. The knox form doesn't seem to differ from any of the others...are you sure it's an SMLE barrel? I know that some Australian Rifle Club MLEs (though not sporters) were fitted with Lithgow Heavy barrels, which had the SMLE length and knox form, but were of Long Tom diameter, though it tapered at the front sight. I shouldn't confuse things, since these are not sporters, but that would be an example of a barrel in SMLE length and knox, but with larger diameter.
The rifle on bottom looks like the same rifle in pic 1 above: the No.2 Pattern. Correct?
Third pic (BSAcarbinesNo1and2 J.jpg): These are obviously the No.1 and No.2 Carbines listed by BSA as "For Officers' Use". They resemble the catalog drawings perfectly. Nice specimens!
