It is difficult for me to tell by the picture, Semi. For some reason my mind tells me it is the model T-5 which Knight had made for them in Italy back in about 93 or so.To me, it looks like it has a separate receiver unlike the Lk-93 which was one piece barrel/receiver. The sights look inferior than those used on the mk I've never owned a T-5 but it didn't have the best reputation and was soon discontinued by Knight.
If that's what it is, I would stay away from it.
I would try to get more info before making an offer.
Twist is most likely 1 in 28.
FWIW,
