Nice catalog, Doctor. I've been picking up Bianchi literature and early holsters for some time, they're collectible as far as this collector is concerned.
I have a catalog dated 1963 with the improbably long Bianchi Combat Action Protector Brand logo, not hard to see why that was an early and short lived effort. After a lot of steady looking I finally found a holster marked as shown. My example was ordered with a safety strap despite being described as "no safety strap needed ".
The next holster is significant to me because it expanded my list of makers that provided holsters to Abercrombie and Fitch. Heiser, Colorado Saddlery and Lawrence were known to me so I was happy to find the Bianchi holster shown.
Great discussion about Bianchi holsters, we even have the designer of many of the well known Bianchi products right here to weigh in.
