Unexpected Christmas present from Police

I added a .17 mod some time ago and when the ticket came back, it just had an extra slot for a generic .17 calibre rifle ha ha. I did for a second consider a new unmoderated .17 Fireball but I told them about their error immediately. It was a PITA as I had already ordered the mod and was waiting to pick it up. Cert had to go back for correction before I could pick my mod up. They did turn it around quick though (same cannot be said for the initial variation)
Always bet to tell the police, had the same last renewal, I sold a hornet a few years back, it was removed from my license when I had sent it back to buy my 6.5 but the variation returned on the new license. It was removed and license back in a week.
