Thanks mate! I thought the middle one was the keeper. Was there any variation between model 1 and model 2 mufflers?
The middle one came off #15,100 , which had a bunch of other model 1 parts on it. Speaking of serial numbers, what kind of date range would that number suggest?
As for keeping the flap, I totally agree. I would love it if it were something rare and "genuine" though!
