It appears typical of many 'teens to 'thirties Holsters which were as 2152hq mentions, sold by Sears & Roebuck or various Hardware or Sporting Goods Stores. Usually there is no Maker Stamp or anything to say who made it.
These tend to be my favorites also...they are usually very well made, good looking, lighter weight and softer than what was to follow post War.
Many could have had a little stouter-wider Belt Loop aspect, but, long as they are not over-stressed, ( and long as the Leather is still sound and not dry rotted or oil rotted ) the Belt Loop part should hold up alright.
So, yes, would be a very nice, and an appropriate choice for a pre-War or between-the-Wars Revolver.
