When I acquired a couple of Diana 100 rifles I emailed the factory and asked if they had ever produced a left hand stock. The lack of response made me think that they were never made.
As ever in the world of classic airguns never assume anything.....
I now have a factory left hand stock which was made for the Mk1 rifle, as noted by the cut out for the sliding cover that releases the pump arm. Note also that the cut out for the bolt is on the same side as for the right hand stock, so I guess no true left hand actions were made.
Right now I am really pleased!!
