But they weren’t made from a crappy alloy were they
You might argue that Arminius revolvers and the Orion 6 are made of crappy alloy, but, firstly, that is only partially true - it applies mainly to their cast alloy frames - and, secondly, the Orion 6 actually looks good and feels good in the hand, as, I am sure, does the Arminius HW9 Target Trophy in .22 LR calibre.
If I understand correctly the idea behind those revolvers, Brocock people did their best to select cheap but well-made and good-looking guns, because, obviously, the adaptation of those guns to the TAC system meant that they would be more expensive than the original live-firing guns.
More importantly from the point of view of rank and file airgunners (I am one of them), they're virtually converted firearms - I am confident none of the Brocock revolvers has ever fired a shot using live ammo, but, with the exception of the cylinder and maybe of the firing pin, the HW9 Target Trophy revolver in .22 LR and the Orion 6 in .22 calibre are exactly the same.
The barrel shroud adds greatly to the overall look of the revolver, of course.
You'd be hard put to find better-looking airguns, in my opinion and, above all, the way they work makes them extremely special - kind of half-way between an airgun and a live-firing revolver.
