Easy to tell them apart when you become an expert, just as my radiographer wife was able to spot the bone spurs on my shoulders in a glance at my X-rays yesterday!
Images will tell the tale. Remember that if you're looking at the basketweave versions, there is little to tell a tale. If the floral, the two eras are VERY different. There are NO plain A.W. Brill holsters.

Wanna know why we holstorians have changed our minds about who was the first maker of the Sunday scabbard? This is one of several articles that appeared at Charles Kluge's death January 1944:

THE CUFF IS ALWAYS IN THE SAME POSITION ON ALL KLUGE/BRILL SCABBARDS REGARDLESS OF BELT TUNNEL WIDTH. The cuff was a structural part of the design's retention system, so for a wider belt the fender was folded further away from the holster mouth; here is an extreme example that is in the book Holstory:

You now know enough to tell me: who made this one, Kluge or Rabensburg?
