Yes in those days '38' meant K frame and equivalents, '44' and '45' meant N frame and equivalents, '32' meant Police Positives etc. Don't be surprised to find that 5-1/2" .45 doesn't mean the SA on Hoyts and Clarks; it means such is for an N frame in 45LC with that barrel length.
In 1934 LAPD's chief mandated that all their pistols w/b .38s only, frame sizes not specified.
The spring of a Hoyt allows the end of the holster to be cut off, because unlike other spring holsters the bend in the spring is not at the muzzle end but up back of the trigger guard.
