I'm in the process of doing a restoration and need some help/input etc. I've got one of the old Pete Jackson vertical barn door style injectors for a 6-71/8-71 blower. It is complete and in very good condition, but there is no barrel valve/distribution block on it. I'm sure that it's going to be all but impossible to find one, so I may have to manufacture one. Does anyone on the site have any photos or information concerning a Pete Jackson barrel valve/distribution block for my injector? I've looked on line, but haven't found anything (especially no photos), but it's possible I'm not putting in the right information in my search. All help appreciated in advance. By the way, I am a machinist by trade, so I do have the capability to manufacture a "look alike".
