Too many assumptions required here. First, presumably a true Model 94, versus the above noted Model 55 'fitting your bill' BUT a longer barrel and nomenclature. The Model 64 referenced, totally 'another' with pistol grip from point of intro in 1932. About that time the "Winchester Proof Steel" (Chrome Moly) barrel for many Winchesters intro'ed. Also for the 94 the streamlined barrel integral ramp sight base. Thru about 1937, a "carbine" stock offered as standard on this newer model. Also, some bluing problems, yet for my money, worth the update advantages. I know far less about the earlier ones going back to black powder era market entry. That before the "Nickel Steel" barrel intro occurring in 'maybe' first few years of the Century? As moving forward from my rifle thirties era, fairly static production of the 94 until production down to maybe double digits from '43 to late '45 and resumed about the same design format. I recall mine as successor with butt plate change associated with moving from Carbine butt stock. Some of course yet with saddle rings. Most not.
A 'net' here with the half tube as most probably not original if your barrel length standard 20". Ever recall, the chances of such as "special order" which was entertained generally 'at a price'. 'Factory likelihood', far less than Bubba's own 'du jour' revamping. I'd be concerned about such as both alteration for depreciated value as well as functioning if original mag spring retained.
The net, net, you've really supplied so little info, my superficial coverage here as 'guesstimates!' And I'm yet an amateur! I'm prejudiced as feeling my own Model 94 sweet spot in that new barrel, old carbine stock era 32 or so to as noted about 37. Notably (unlike the Model 64 from inception) these era 94 carbines NOT drilled for receiver sight side mount. That a "strict collector" as irreparable tilt. For great shooter and negotiating point, to save $$$. As speaking of side mount, to a true collector... "Truck rifle!"
A 'parting shot' about a rare factory variation of latter twenties as authentic "barrel clean-up model with reused Model 95 barrels. Very rare. I do have one but even if such, the rifle you described as moved only to "rare truck gun". Sorry for frankness, but so many guns from woodwork with side mounts. Same story across myriad Mfgs and models!
Good luck & Best!
