I am pretty sure it is 87 not 67 as year of Mfg. if you look closely.
A.I. says the 24 at the first of the one serial number is the maker and therefore a Josef Just (maker number 24). Says the lack of deep relief sides is called a “Slick finish” versus your deep relief engraving.
A.I. says the following:
That description confirms you have a
"Freischwingender Lauf" (Free-floating barrel) design, which was the cutting edge of Austrian drilling technology in the late 1980s.
In the 1980s, makers like Josef Just moved to this design to solve the "climbing" problem. In traditional soldered drillings, as the rifle barrel heats up from firing, it expands; because it's attached to the cold shotgun barrels, it literal bends slightly, causing subsequent shots to hit higher and higher.
I suspect the ported free floating barrel didn’t exist in 1967 and must be an 87. I think a non rimmed round would have also been much more likely in a 1987 vs a 1967.
A black finish was called a Schwärzen finish (a charcoal process finish back first part of 1900-WW2) but I think this 1987 model is a modern highly Polished black oxide finish, and not regular bluing. It is a deep black finish (think like a deep polished Black Korth Pistol). I read this is a much more tedious finish as the metal must be perfect where as engraving gives a lot of forgiveness on a coin finish traditional gun. I have a 1935 Funk drilling in the schwarzen charcoal process finish and it is not as polished and reportedly should not use any harsh solvents which will rapidly diminish the black finish. This gun has deep relief carvings across the top back of receiver at the locking bolts which are large ivy leafs(almost like sweet gum leafs) but the side is lightly engraved at the perimeter and the bottom and trigger guard are all just highly polished black finish.
If this is a 1987 Just Drilling, it is indeed a strange and rare custom gun. No mounts. Black Finish, Ported Free Floating Barrell(the end is reamed out and wide at the point of the ports), a non rimmed cartridge, a white dot on the rear sight, not highly engraved like most Just. It is in mint condition with no rust or finish discoloration(another reason I think 1987 as a 1967 gun just probably wouldn’t be in this high condition.
I shot it today and it is shooting high the way I usually align an iron sight. I suspect it is the target bullseye needs to be sitting fully above the aligned sight as opposed to the target alignment being at the edge of the top bead on point of impact (this is how I shoot and it was a good bit high at 100 yards).
Anyone think they can agree it is a 1987 Just? (the 24 being maker number.). I don’t think it is a Fanzoj as nothing there to support that. But I will not complain I got a Just! A.I. says it would have been a $5-$7k gun brand new in 1987 (14k-20k in today’s money!!!). It is just insane how the price of these fine German and Austrian guns are at post WW2 all time lows.
I haven’t been on the forum in a few years but got several I need to put on here and get more info about.
Thanks for input. Hoping for confirmation.
