N. Lajot was a reknowned Liège gunmaker of the 1st. half of the 20th century. His production of fine s/s - o/u doubles (shotguns & rifles) was highly esteemed and I don't believe he ever made anything but handmade top grade guns. I take it that your sidelock 9,3x74R must be representative of his trade.

I've only one daughter and, to my knowledge, the only older man she's attracted to is her father
