I've had this Peterson pipe for about 15 years. Got it used. It's always been an anomaly to me. I believe it says Made in Ireland (actually kinda looks like England, but I know that couldn't be true)-so that makes it pre '49, Also Peterson of Dublin, but here's where she gets interesting... It is marked "K" on both the stem and tenon. It clearly did not ever say K&P. It was always ever just "K". Also, it is sand blasted. I've only ever seen rusticated Petersons.
