In 1939, Sept-Oct.  the club held a Course C Qualification Match.

Does any one know what this it?

The way I read this, it is a match held at 200 yard distance.

String 1: 5 Shots Kneeling with sling optional.

String 2: 5 Shots Standing, with hasty sling.

String 3: 10 shots in 60 seconds, standing to kneeling

String 4: 10 shots in 70 seconds, starting prone, running 25 yards, and back to prone to shoot.

Really? Run 25 yard and then shoot? It also looks like the running is included in the 70 seconds.

(See Hasty Sling use below)
