NY: Came to this late....my eye is pretty good as I guessed it a Grisel action,and as if you needed any encouragement (LOL!)the price is easily right. Glad you grabbed it.
I had an Ottmar 300 Win Mag on a Burgess 1909 action that was one of the best customs I've owned.You made a great snag and I'm certain you will be happy with it.
Ottmar built fabulous rifles.
