I've got one that was made in 1937; as far as a target rifle, it's among my favorites. I acquired it from a friend who has a cowboy/military/unique firearms shop well over 10 years ago. Mine has a cobbled-up addition to the rear sight that is definitely non-standard. Mine is the only one I've run across since I purchased it.
You're absolutely right in that it's heavy, Jerrywahid; it's built like a Munich bank vault door. Mine has 3/8 in rails milled into the top of the receiver. Shortly after I got it I found a nice Weaver V-22 2x6 scope with rings that looks pretty good on it and is fairly authentic to the vintage of the rifle. Lovely honey-colored wood with a fine figure to it. Checkering is still nice and sharp after 60+ years. I do not know how it came to this country, but my suspicion is that it may be a WW2 bringback. Perhaps tomorrow I'll get it out of the safe and take some photos of it to post.
Regards,
Rabbit.
