I don't know if the rifle on Gunbroker is a Hawken or not. I'll leave that to the experts. However, I was struck by its similarity to a rifle that
is marked J&S Hawken, which was shown on the Ambrose Antiques site as well as Cowan's auction site in 2017. Here are a couple of photos from Ambrose, which I saved in June, 2017:
View of the lock. Note the acute angle in the lockplate just ahead of the bolster. Also the brass scroll triggerguard, and single trigger.
Full-length view of the off side. This rifle was described as having a walnut stock and a 34", .50 caliber barrel. The same rifle was on the Cowan's auction website starting in February, 2017. While Ambrose Antiques took down the page with this listing, you can still view the rifle on the Cowan's website:
J&S Hawken FullstockInterestingly, Cowan's said the rifle is .41 caliber, and "Property of N. Flayderman & Co." Ambrose said the rifle had "impeccable provenance," but did not share any details. Anyway, here are a couple of views from Cowan's website, that were not shown by Ambrose:
The tang is short. You can also see the
J & S HAWKEN stamp on the top flat. The Ambrose/Cowan's rifle has a hooded front sight:
For comparison, here are a few images of the Gunbroker rifle, described as .45 caliber and 55-1/4" OAL. I'm guessing about a 40" barrel, described as a "Full octagon, heavy barrel." In this close-up of the lock and breech, note the same acute angle in the lockplate, as on the Ambrose/Cowan's rifle. The triggerguard is different, although it does have a scroll and it is made of brass, so it is superficially similar to the guard on the other rifle.
This photo shows part of the cheekpiece. Note how the incised lines are not parallel, like on the other rifle:
So, there are some differences. The sideplates are different, one rifle has a patchbox and the other has a hooded front sight. However, my general impression of these two rifles is that the stock architecture is very similar, with the wrist looking too thick in the vertical dimension. Both have deeply curved buttplates, brass scroll guards, single triggers, and heavy octagonal barrels in rather modest calibers for Hawkens. I won't get into the debate over whether either or both rifles are genuine Hawkens, but I would consider the possibility that they were both made by the same builder.
Offered for your consideration.
