Grease gun. Not the M3 submachinegun nicknamed as such. An actual grease gun. Due to the Orkish power of belief, this is just as effective.

Meat Gun!

It looks like the kind of weapon you get when the ADHD hyperfocus Ork meks function under fades half way through the project, they dig it up three months later and then keep working on it having completely forgotten what it was originally designed for. So my answer: all of those. Its a bolter with a lasgun mode that also shoots fire.

Plasma or gravity

warpbubble gun

It's a Heavy-Bolter-Combi-Lascannon with an attached flamethrower tank, because *ORKS!*

It's a flamer. Hence the fuel tank on his back connected to the weapon via a pipe.

Fart gun, back on the trukk is a trio of gretchin just taking turns farting into assorted cannisters

Oop painboy?

He's a MekBoy holding a grease gun.

Buble riffle

It's probably a flamethrower that throws las-bolts instead of flames.

I thought it was a conversion beam

Thats gotta be a plasma gun

Squig Juice Gun. It's not a gun yet but it should be.

Ork custom blaster, Switch between flamer, Lasercannons and plasmagun.

Flamer? Pee shooter?

Snazzgun

It's a gutblaster, a handy universal weapon to use as whichever weapon you want it to be whenever

conversion beamer

Squig-Brew delivery system.

Its a potato cannon. Fueled by mash from the tank on his back.

Screwdriver.

All of the above 😅

Flamer makes the most sense of the three

There were so many wacky Orks back then who knows? I’m finding so many weir minis right now going thru my old box’s.

Plasma? Those on tops seems like coils...

Clearly a power sword

A plasma flamer

Clearly, a Webber 😄👍

with the pipe from the tank on his back my mind goes to flamer

Sounds like Flathead has a kustom shoota

Pneumatic riveter

Heavy glue gun!

Grava-mekktic supa-shoota

I'm gonna throw "plasma gun" in the ring to further confuse things--paint those ribbed bits blue, and yeah?

Hold up, hold up, hold up with forgetting a very important thing.This isn't an ork that done could very well be all free.And they just pick and choose what fire any moment.By believing it is the thing they want to fire

It is a flamer because it has a fuel tank linked to it

A flamer, the hose goes to s cannister.

Plasma gun?

Ork wiv a D Kannon!

Looks like a flammenwerfer to me, cause it werfs flammen

A speedy bit of dakka, since the gun tank is red.

Squig beer sprayer!

I do like the idea of an Ork running around with that weapon, shouting "CHOOM" and immolating foes simply because he believes hard enough.

Meltagun !!

Victorian fire hose muzzle

Industrial Greases Injector. Its not a weapon. Its for filling the the engine bays of ork vehicles with lubricant to help keep them running.

Paintball gun

Great sculpt! I would never have guessed it was from Rogue Trader.
