What it says on the tin.:p

I know gunpowder rockets have their limits, but solids up to the performance of the SRB have appeared. So, how credible is it for advanced solid rockets to appear by 1900? (Or before WW1.) Something like the front-nozzle (or front-engine, rear-warhead) design? Or "hollow-core" types? Or burn from the top models? (Or a combination of all of them?;))

Beyond that, how difficult would it be to develop a *thiokol motor?

In short, your challenge is to make a better R4M or FROG ready for use in WW1.;)

Bonus points if you can give them wire guidance.:p
