Given the introduction of very basic modern technical knowledge of all colors into a much less advanced, but still steel-using society, I wonder how practical a simple-blowback black powder submachine gun could be.

Depends. If we're at the 1632-type situation, you're going to need reliable primers and metallic cases at a bare minimum; neither is especially simple. 

[Amperzand]

That does seem to be the main issue, yes.

The cases and so on would be the most difficulty part to manufacture.

I suppose one solution would be to create sort of cardboard shells using waxed paper or parchment. For primers/ignition, I suppose one answer would be to install a very simple hand-cranked electrical system to ignite rounds in the chamber using electrical sparks, crude generators and batteries being extremely simple to make in theory. It'd make the gun itself considerably heavier and more expensive, but potentially save a great deal on ammunition.

Obviously the flimsy shells would require fairly anemic loadings and low rates of fire, but that could be bypassed in a few ways.

Alternatively, something akin to very long Rocket Balls could be used, still with the spark igniters.

Well, if you could harden the parchment and re-introduce certain fibers that were lost or weren't lost in the timber>parchment transition, then you could create a strong enough shell hypothetically. As far as primers and making it more easy to load and fire, it's simple, I would figure you'd do the exact same thing that they do with firearms just with what's available. If your using metal pipes to craft the barrel, magazines, or what have you, then you'd want to install a firing pin in the chamber and possibly something in the magazines so that when they are loaded a spark will go off. Note that the disadvantage of this plan is that every time you load a magazine it would fire a bullet to de-facto start the reaction, but anyone with a hint of experience with firearms wouldn't have a problem pointing it at the ground when they load it. It would probably be very prone to jamming depending on the quality of the magazine primer's.

Incendiary torpedo.

I'm imagining two shaped charges and a hell of a lot of napalm or whatever was made to replace napalm. WP instead? FOOF?

The first shaped charge opens the hole while the second delivers the package through said hole.

Whatever that stuff is which reacts with water. Gives you a river of fire rushing in.

Although most things I've seen hit by torpedoes haven't lived to see a secondary effect.

[Amperzand]

I think torpedoes are generally large enough to carry sufficient straight explosive to down most targets. A few battleships famously needed multiple hits to destroy, but beyond that, not a lot of need for extra-scary torpedoes.

[somemildmanneredidiot]

So the primary purpose would be for striking ports then, though if you're torpedoing ports then something has gone wrong logistically and stragically then most likely.

[Erkki]

Russians do have torpedoes with nuclear warheads...

Could make some kind of anti-personnel torpedo?
For when you wanna reclaim the submarine.

Maybe some kind of enhanced radiation device, but water is fairly radiation blocking and actually reclaiming the subway once everyone is dead would be problematic.

[Rolepgeek]

I'll bet you a sodium torpedo would be pretty effective for what it was trying to do.

Not sure what that would be, but still.

[Tack]

Maybe a barbed sabot?
We don't need water to get in, after all.
Bonus points if it's a lighter-than-air lethal gas. Instant ghost sub.
