Hi Malcolm, I do have plenty of projects now! I am sure there will be more out there I just have to buy. It wont be running by the time your here but you can run the K and imagine it has a single front!
We have been working on collecting some numbers for the 12-20's concerning the extra 4 numbers that are stamped onto the block. We do not know yet what exactly they stand for but here are some numbers Ervin and Joe have collected for me.
So far I am thinking the first number stands for the year of production. 1 means 1st years of production 2 means 2nd year and so on. I think they started with 1930 models so a 1 might mean 30, 2 means 31, 3 means 32? At this point it is all guessing but increasing serial numbers the first number always increases. same with the last 3. They increase with serial numbers till thefirst number changes. So heres a list and lets see if we can come up with a sounds theory on what it all means!
