Let's play the name game!

Farm Collector received these photos of a corn grader and the following letter from reader Harry Roland:

"I am restoring this seed corn grader, and need information about what the name is. The letters that can be distinguished read O - - I - N S. The middle letter could be an E, H or K. This device could be about 100 years old. I hope someone can help in its identification."

Do you know what the name is? If you do, leave a comment below or contact Mr. Roland at dhroland@windstream.net. 

Do you know anything about roller restoration? Farm Collector received this letter from reader Norman Roering:

"I am restoring a land roller and need some help. It has three drums. Each drum is 24 inches in diameter and 32 inches long with a 1-3/4-inch hole in it."

If you can help, please contact Mr. Roering at43512 Co. Rd. 19, Belgrade, MN 56312; (320) 254-3452. Or leave a message in the comments and we'll pass it along.

Gas Engine Magazine reader Kevin Stier recently sent in these two photos of a mystery air-cooled engine he bought at auction. He's searched high and low for identifying features but has come up empty. Do you have any ideas as to what this antique engine might be? Post your ideas in the comment section below.

This week's Old Iron Question comes to us from John Petty, who would like to know the following:

"Could you tell me how many drops of oil from a drip oiler should drop on a piston per minute on a 2 HP hit-and-miss engine at idle?"

If you can help John, post your response in the comment section below.
