Is This 'Sinistral'?
 

I briefly owned this well used Parker a few years ago. The stock was cut away to allow the shooter to use his/her left eye, but shoot right handed. Sorry for the poor picture. It is a 'picture of a picture', but it shows the cutaway and the missing recoil pad. The serial number is 153398. If I had known then what I know now, I may have kept it and looked for a replacement stock. Aside from the wood, nothing else was modified.

As I recall, it was or is a DH grade with a standard stock that was cut away. The gun I am familiar with was not originally made as a sinistral stock. When I put it to my shoulder, it would not serve as a gun to shoot from the right shoulder and the left eye.
