Along with the barrels, it's a good bet that the Navy rear toggles/sights were added later, too. The first one ought to make a great shooter, it has been over-buffed as prep for a refinish. The AE would be a good candidate for at least returning it to original configuration (barrel and toggle) at which point the Navy toggle and Carbine-length barrel on it could be re-sold to someone for a project. Or just shoot it the way it is--you're already halfway to the target!

Value? My guess is that each might be worth around a thousand, maybe a little more, as interesting shooters if they function OK. The condition/value--due to the refinish--of the first one is not as good as what remains of the second pistol.

Lastly, do not attach the butt stock to either pistol, as the combination makes either one a "short barreled rifle." It is against the law, unless the weapon is registered as such with the BATFE. There are exceptions, but these are not in that category.
