Good Morning Gents. I have just read on line a copy of OU2567 Ammunition Pocket Book 1924. All standard stuff but the reference for the 1'' Aiming rifle stumps me. It states that the 1'' Cordite rounds had an orange patch and the BP rounds a white patch. I have never seen any reference to these cartridges being patched before. Has any one seen a patched Aiming Rifle round. I would love to see a photo. Regards David.
