There were many different builders of rifles on the Lee Speed actions and many different stock shapes and as they were generally custom builds this is understandable although there were "factory standards" from BSA in the sporting rifle in the same way there were officer models in the military configuration.
This one was sent to me from a friend in the US to have buff horn added to the forestock and grip cap so I though I would add a few pics of how that was/is done. I had instructions not to be concerned about the necessary sanding on the checkering as it was going to be re-cut.
