The handcrank machine is a very nice looking Singer 128. You can find it's age here:

I wouldn't snub those decals. It's a great looking machine and the original crank is a very nice bonus. I like hand crank machines, they're nice for fine work. If you know any kids that want to sew a hand crank machine is perfect. Kids love using them.
Your Fleetwood is a nice looking Japanese Singer 15 clone. The JA 19 number is a manufacturer code. Someone here can probably tell you who made it or at least where to look to find out.
Congrats on your new machines!
