yep , they are out there, but they are double tough to find.
collector's Firearms in Houston, from time to time, has 1 or both. but you will pay for them, especially if the carbine looking one has all the correct pieces there to the rear site, which usually get knocked off and lost.
looka that mag in the pic, way longer ( or wider) for a 22lr round, this mag is easily seen
as a 22 mag round mag.
