This edger/trimmer was in my grandfathers tools, my Dad inherited and I got it from his estate in 1999.  There is a number embossed on the inside of the casting- 3TSNBL.  I could not find reference to this number despite the fact that American Lawn Mower Company has been in business since 1895.  I hate to part with this piece of my history but I don't have enough space to continue storing this tool, want someone who has a passion for the old tools and has space.  There is a small piece of the tire casting missing.  Turns freely and the tire is intact (surprising fact given its age and use!!!).  
I will ship  the mower/trimmer dismantled in two boxes, 1 for handle and one for reel portion.  This should save on the oversize dimensional shipment pricing but adds a little due to 2 boxes.  Sold as-is, no return and no warranty.  As always, questions will be answered quickly.  Ask for more photos, if needed.  Thanks for looking
