In November 1973, I went up to Everett, Washington to look at a 510 Avery that was part of the Ed Currens estate. Ed Currens was the first president of Antique Powerl and in Brooks, Oregon. When I became dissatisfied with the Avery as it was extremely incomplete, I started looking at Ed Currens' 1918 15-30 International.

After some deliberation at home I decided to take the second trip up to Everett, Washington, and bring home the International. We hauled the tractor home in November 1973 on a double axle trailer behind a one-ton truck. I knew that I had my work cut out for me as the entire tractor was a basket case.

Before I started work on the restoration of the tractor I needed some information. Some of what I found out was that there were only 500 of these made with the cab. The tractor has a 5 inch bore and an 8 inch stroke. It has a 4-cylinder engine cast in pairs, cross mounted with the cylinder coming back into the cab. The engine runs at 575 rpm with a top speed of 2.4 miles per hour. It is 15-30 horsepower with the final drive chain enclosed. The tractor weighs 8700 pounds, is 8' 10' tall and 6' 6' wide. It has 4 car buretorsone for each cylinder.

The following spring I started working on the restoration of the tractor. The first thing I did was to completely disassemble the entire tractor down to the frame. I gunk-tanked all the pieces and then sandblasted the wheels and all the parts. I then painted them with primer. I reconstructed the cab, as all the sheet metal was completely rusted out. I then reassembled the tractor again and began by rebuilding each individual part as I went. There had been no radiator or water tank with the tractor. So with measurements and a picture of one from Canada, a friend of mine built one from scratch. I painted the tractor and parts myself as I went. On June 18, 1983, we finally got the finished touches done with the help of a few friends.

We proceeded to start the engine. We hauled in a 12-24 Hart Parr and belted it to the I.H.C. and turned the engine for about thirty minutes, then shut it down to see if everything was okay. After some minor adjustments, we started turning the I.H.C. engine again with the 12-24 Hart Parr. I decided the time had come to start the I.H.C. engine. So I opened the carburetor on number one cylinder until it fired and continued to fire, and then moved to the next cylinder until all four were firing, then let it run for a few minutes. Then I removed the belt and let the I.H.C. run on its own for about two hours, then shut it down. In about one hour we decided to try to start with the hand crank. On the second pull of the crank, the engine started.
