Stout Auction is up!

Check out the new Stout Auction - it is out on their website. I noticed a couple of standout items.
The first item would be the #7. I strongly believe it could be a McCoy #7. That would make it rare by Postwar Standard Gauge standards. It's a nice loco too. I am partial to thin rim #7's myself. With these getting rarer and the casting aging, this may be a great loco. I'm pretty sure it isn't a Cohen and there weren't many other folks reproducing these.
The McCoy Circus set caught my eye as well. It says in the description no couplers are mounted on the cars. I know this is a McCoy Circus set and I know that McCoy shipped the set with couplers. So why no couplers on this set? McCoy collectors, maybe you can illuminate me!

Last but not least this little Marklin gem. It is standard gauge. It has some repro stuff on it as well as a new paintjob. Even still, does anyone know the history of this loco? What kind of set was it a part of? Is it standard gauge or #1 gauge?
