Have a look at this.

Harmonica guns are pretty rare and to see one being fired is rarer still (on the blog link above).

[Woftam]

Interesting rifle. What caliber is it in ?
Here's another one with a slightly different approach, the hammer slides backwards & forwards.

That's on sort of firearm I can't get excited about I am afraid, they always look so cumbersome to me.

[Aughnanure]

Those five shots were in 30 seconds, imagine meeting up with that technology in 1840; and then he puts in another chamber bar

[Niner]

The hammer back and forth one that Woftam shows doesn't make any sense to me. How could you load three charges in the same barrel and move the lock back and forth to fire three individual caps on three nipples? Wouldn't firing any of them cause the rifle to blow up?

[Aughnanure]

Those multiple nippled guns are very rare, cost was a factor but so was forgetting and firing the backmost charge first (or so I'd imagine)
Quite safe if one fires the front one first as BP doesn't usually ignite from compression.
Never fired one myself but have fired multiple loads in succession in a Roman Candle gun which I and the late Linton McKenzie built using a piece of seamless drawn tubing for a barrel.

Roughly thusly:

Fires VERY fast

Bye the way, Graeme, is that one from your collection??

You would have to know EXACTLY where the powder was in relation to each nipple though

[Aughnanure]

Marked ramrod, same as for the single nipple on the Roman Candle gun.

Always preferred the two nipple models (f) myself.
