Yes, quite an indicated match.

Completely a different universe; in generation, shape, technology.
But don't be lazy; browse the Net

Ah but I 'm not retired , any how, I will consider myself told off and go and browse the net. However I have to say that I prefer the wisdom of someone like yourself who I perceive to be an authority , rather than the unsubstantiated stuff one often encounters on the internet !

Man, i know nothing; don't be surprised if someone comes after me and says i am wrong
I am comparing yours to mine; although mine is larger (51/2"), the approach is the same.

During your browsing you may find these 'grenade launchers' or 'portable mortars'. They date from the 18th century, but i don't think they are the issue here.

Grenades vs mortar shells...this has always troubled me as well. Per Gilkerson, grenades were rarely smooth and often not even perfectly circular, because they didn't need to fit perfectly in the barrel. Mortar shells were more like solid shot in that they were supposed to be well formed and smooth, at least theoretically. Put one in the ground for a few centuries and it might not be so easy. I have what I think is a grenade in my collection, somewhat between the size bigger than a golf ball, but smaller than a tennis ball. It has a very small 1/4" hole and congealed powder inside. It isn't perfectly round, so I assumed grenade. Problem is, most resources claim grenades are larger than mine and with a bigger fuse hole. Hope to someday find a resource that shows other sizes besides what 'Boarders Away' lists.

Another controversy is with the brass grenade launchers. Some sources say that these rifle types were too short and too thin to be effective as launchers and that these guns were more likely for shooting off flares or fireworks.

do a forum search here on 'mortar shell' and 'hand grenade'

Speaking of which ...
This example is in exhibition in the Portuguese Royal Palace of Vila Viçosa armour collection.
For what it is worth, the text says that it is a XVIII century Spanish (?) portable mortar, with a 73 m/m mouth. Cast in bronze, with a chamber of much narrower section, with a support hook in the lower part. Silex lock a la French. It shot 'case' with multiple projectiles. It was used in ships and parapets.
