I'm new to this site but love tin plates, especially American Flyer wide and O gauge. I picked up this set today and found out through a few Facebook groups that it is an American Flyer 1347 Merchant set. The nice woman I got it from said it has been in her husband's family forever and has spent the last 35 years in their closet. It also included a Lionel 820 Searchlight that had been modified to use Flyer couplers. When I got it home it ran on my test track right off the bat! The drive wheels look different than any others I have seen. Has anyone ever seen replacement wheels like this before? I just need a replacement light and a good cleaning and lubing before I run it around the track. Any information about this set would be greatly appreciated.
