Probably will Andy!
H, I'll see what I can find on Chow Hound - think I've got soem info somewhere. Yes, the top turret drops into the 'hole', then twists to engage. the ball turrret can be clipped into the gimble of the yoke afterwards or, if you're careful and gentle, the whole yoke, complete with turret, can be pushed into place from below, until it 'clicks' into place. It makes lif a lot easier for masking and painting. It's always worth looking fully at the instructions and the parts, to see what can and can't be done later, then planning ahead, with modifications to the build sequencxe if needed - makes things easier sometimes!
If I can't find any info on Chow Gound, have a look at the Bomb Group's Association or Veteran's web-site, there might be a lot of info there - I found the name of the B17G I modelled, after looking elsewhere for about 20 years! Also found a pic of it's nose too! How did we manage before the Internet??!! Months or years of searching books,film footage, libraries, museums, veterans interviews etc - that's what!!
