I'm trying to identify the item shown in the first part of this video.

I found some info which maybe help,though doesn't tick all the boxes.your little mexican war howitzer could be a sample from foundry in pursuit of supply contract.Following info comes from....David A Norris 'American's Civil War' of Sep.1995. is about Mountain Howitzers first delivered to US Army in 1837 ordnance manuals refer to them as Model 1841.Were used in Mexican War and Indian Wars. Main manufacturers were....
Cyrus Alger & co. of Boston and James T Ames of Chicopee  both of Mass. 
 The bore was 4.62 which fits well but barrel length was 38 inch which doesn't.If you can have a sniff around these two manufacturers, maybe hit pay dirt..........or curse Scotsman.all depends on how curious you are

Thanks.  The US mountain howitzer you mention was almost a direct copy of those already in use in France and Spain, since sometime ca. 1820's.

The shorter howitzer I show in the video has no rimbases.  That and other clues tell me it was probably made pre-1800.

But beyond that I have no idea.
