Hi James, it wasn't that long ago that I bought 2 x 20yrd gauges one for me and one for the club from the NSRA online shop. I had a look on their website https://www.nsrashop.co.uk/collections/scoring but for some reason its not listed now? I would give them a call or email as they may have one in the shop or at the very least let you know when they expect to have them back in stock. Peter
