Spring Type Adjustable Tension Duty Holsters (e.g Don Hume H702)

[mtice]

I have been looking at vintage spring type adjustable tension holsters like the Don Hume H702 holster with adjustable tension screw and removable retention strap . Can anyone tell me when these types of duty holsters became popular? Was this a 1970s or 1980s style duty holster?

I like the term, not original to me, "spring - post" to described this style. Original design 1930's by Ed Clark, who also designed the spring holster usually thought of as being by Lewis.

Popular in uniform and civilian clothes well into the 70's, both cross draw and straight draw.

Made by just about everybody but Bianchi and Safariland. Bucheimer made several variations. Bucheimer-Clark made both styles. Bianchi used the X-15 type wire spring while Safariland in the 80's used the Lewis style spring in holsters designed by Clark's son Earl.

Correction: in another discussion, Red agreed the screw does adjust the clamping force of the spring. I may have misunderstood before.

Here are a few of the spring type holsters that I happen to have.
On the left is a Viking 55M shown with my S&W Model 29.
2nd is a Hunter 55L shown with my 1911 Colt's Gold Cup.
3rd is an old ad for the Hunter.
4th is a plain little black one by Brauer Bros. with my Model 10 2" barrel.

Heiser made one , as did Smith & Wesson.

This one is marked G.F. Cake, a well known police supply company-it was made for a Colt pocket auto.
