That crankshaft is salvageable. There are places that can build those journals up and then machine them to specs. Spray welding is one process used for this purpose. Take a look at this thread as there are a number of businesses listed that can help you.

Spent a little time looking. From what I can find these were built 1911-1917. I'm thinking the brass rod ended in 14 or 15. It woud be worth a shot at the crank. Start sanding it easy and watching. There is also an acid that will raise the stamped numbers since that metal is compressed harder than the metal around it.

 

What is the name of the acid?  I'm also thinking of try electrolysis to clean up the rust on the flywheels and governor parts. At some point I will need to pull the flywheels off of the crank.

Ok it looked bigger in the pictures,  Sandblasting would really make them shine.

Awesome find and I am subscribing to the thread to see it's progression. I love seeing the hit and miss engines at the shows and listening to them.

Spray welding is something I just heard of about a month ago.  I was told its expensive, its worth it if repairs it. Learn something new every day.  Great to see it getting fixed up. love the sound of the old engines running.    Noel

You can also have the crank journals hard chromed and reground to size.

Here is a good site on restoring serial numbers. It shows the most common used solutions. not sure how much of this the average person can buy. I was given a small amount of solution years ago by a detective checking a car in a dealership I was working at to help see a serial number in an old tractor. It worked good.

Be cautious what acids you use....I know for a fact vinegar will eat cast. I have vat of vinegar for cleaning rust off of STEEL parts only...I put a brake drum in there for a week just to see what would happen....I could peel layers of the inner drum out with a putty knife....
