It's just that the little things remind you. The other day it was a call from a friend about Bren barrel nuts and I remembered a small MI (that's a miscellaneous instruction) that came out that allowed........... anyway. It's the difference between the old, long time-served ex apprentices and the amateur enthusiasts. If it's not written down the reality and reasons get lost and the myths perpetuate. Have a great rest of the day and thanks for the kind compliment
