Oh yeah, I'm gonna run for the nearest public library and see if they have a book on the thing!
Actually, just about ALL SMGs are Schmeissers, when you get right down to it. MP-28 was a product-improved MP-18I, Lanchester was a copy of the MP-28, MP-38 was a mass-production variant, MP-40 was easier to make, Sten was a super el-cheapo job, that's all.
They all work the same: straight blowback, otherwise called Spent Case Projection.
And yes, the MP-40 is VERY controllable. Just watch out for that 200-metre rear sight when you are shooting closer ranges!
