Sean,
Are you looking for members to post a pictures of machines and corresponding serial numbers?
If so (And this is just my thought) If you have time and patience for such a huge commitment then perhaps pm's to you would be the best way to go. That way you could then use the info to compile a list. You would need to be careful to ensure that the engines are original to the particular base. All too often now older machines have had their engines replaced either with a different one altogether or a newer/older version resulting in a serial number seemingly out of sequence. Manufactures may also have changed the engines under warranty either on a small scale like one or two machines or a large scale like the victa twins.
A mammothly huge but worthwhile project to dedicate the rest of your life and lives of your children and your childrens children and your childrens childrens children to and well I could go on but you get the idea.
Maybe pick ONE model, get all the numbers and photos of that model then move onto the next. You can't compile a list without an enormous amount of data. That kind of data and photos in the compilation process would clog up the forum.
Of course I've never even thought about possibly maybe tinkering with the idea of compiling a list one day.
If you do go ahead with this project I wish you luck and it could really benefit future generations. I want all my machines to be given to a museum one day for record keeping as we have already lost FAR too much of our engineering history due to thoughtless destruction. We need to save what we have left. This is OUR history and what a sad thought that when this generation dies off all that will be left is pollution and landfill showcasing what a disposable society we have become!
