Almost all the IJ rifles were German-made... it's hard to tell which one you've got since they made lots of ten-rounders.
At any rate, unless it's one of their M-1 Carbine .22 copies, almost all are valued at less than $150 in perfect shape.

Not many of these were made... the markings may say "Plainfield"...
