Anschutz did make a number of left hand rifles, and I think they still do. However I don't remember the rite hand action in a left hand stock (I am not an expert on them). I looked for an Anschutz in left for a while, but too much money for me at the time. CIL sold some Anschutz models stamped CIL on them for a while, as per yours, and I had a clip feed lite sportster for a while (rite hand). Others may have been offered?
Some rifles fit well to left hand with a rite hand bolt, however generally not good for speed, as have to move it away from face to cycle.
Yes it is possible to glue up pieces to make the butt or a stock if wanted. Rough out with angle grinder, chisels, planes, axe, etc. IF the person doing the copying can do the inletting after the stock shaping, may allow the glued model for stock shaping, then original stock put in machine for inletting. Or vise versa. Doable, not sure, might need a little extra messing about or a few mula more.
Hold the rite hand stock up to a mirror to see what it should, may look like.
If there is a biathlon team around, someone may have a lead for a stock also, as Anschutz is common for some, and there is likely some leftys there. Some have switched to a Russian? rifle action, with Anschutz barrel and a linkage for leftys to work a rite hand bolt as Anschutz appeared to have a problem with bolt handles coming off in very cold weather.
They say leftys don't live as long as rite handed people, small wonder, remember skill saws and drills with locks for the triggers that locked when used left handed.
My daughter learned to shoot left or rite as she felt like at each time. Some things I am not sure which way to do, so just do it. Went golfing one time, rented clubs. Went out with one rite and 2 left clubs, still don't know weither I am left or rite handed for golf, that's O.K. as my dog knows more about golf then I do. And he's better at it.
