Melling 201 priming tool and the LA

First engine I ever built was a 340 to go in my 70 Duster, in 1975 when I was 18 years old. I took the old shaft out, and ground all the gears off of it to use as a priming tool. I just sawed a flat screwdriver off to put in the drill and prime it with. I still have that same old shaft and sawed off screwdriver in my tool box, and will use it on my 273 to prime it sometime in 2021. :D
