I'm cleaning out the barn on my property that been in my family for well over 100 years. I've found all kinds of cool stuff. Some I know, some I can guess, but this has been one of those that google don't even know! We've had 1000s if different cars, trucks, tractors, motorcycles, and anything else with a motor come along in the may years my family has lived here. So when I uncovered this "new" old muffler I had no clue what it was purchased for. It was still in it's box but it was trashed and the lable was gone. But the muffler itself is like brand new. There's no Hallmark or company name stamp anywhere on the muffler but there are some numbers and a few letters along with the word inlet on one side. I'm including a few pictures so hopefully that will help but if anyone has a clue and needs more pictures please feel free to let me know. I appreciate anyone's help that can help me solve this mystery. Thank you very much
