In answer to a question on the original size of the old 10 mt target, I searched out an envelope I knew I had somewhere with samples of old targets.
What I had forgotten was I had a sample of the old 18ft (5.5mt, wow! early days of decimal!) ARCA (Air Rifle Clubs Association) rifle target, this was the forerunner of NARPA (National Air Rifle & Pistol Association). This target was a paper representation of the Bell Target and ARCA and NARPA was midlands based, started by Denis Cummins.
We only shot NARPA for a short period in the very early 70's and then specialised in 10 mt and still do. You guys probably know all about this and already have samples of these targets but If any does'nt and wan'ts a scan give me an e on robin.carter80@ntlworld.com
Good Shooting
