There is a lot of talk on other forums about putting a big stack on the 4-4-0 and the balance. Here she is with a PSC Hunter-Radley:
Obviously way too big, sorta like one of those Hollywood "backdated" locos.
The 4-4-0 ran the same with that much weight on the front with no balance problems at all.

Hi, Harold,
Now you know why so many 19th Century locomotives had those ornate-bracketed headlight shelves sticking out from the front of the smoke box!
Actually, the extension of the smokebox forward of the 'shotgun' stack is intended to catch the cinders that industrial cyclone is also intended to catch. Huge cinder-trap stacks usually were used in conjunction with smoke boxes that ended just forward of the diagonal braces to the pilot beam. Having both is a belt-and-suspenders situation - unlikely, but probably not unknown.
My personal favorite prototype 762mm (30") gaquge loco, the Kiso Forest Railway 0-4-2T, has a short smokebox. Originally built with a cabbage stack, it was later fitted with a huge cyclone stack like the one in your photo. The stack is almost as big as the (miniscule) boiler.

I used that stack because it is the heaviest one I had. I was demonstrating that the locomotive can carry a heavy stack without losing balance.
well Harold , i think that engine needs a little more work before it goes on the layout full time
it's certainly going to have charactor when it's done
