Bayonet ID help

[Louisville]

Hello again. This is the last of the collection that I recently purchased and included two bayonets. I'd love info on model and potential value. The one marked US is the shorter of the two. Thanks for any help you can offer.

This is a great resource

 

[Old Soldier]

The longer one is a British Pattern 1876 socket bayonet for the Martini-Henry.

On the short bayonet, can you provide the interior diameter of the socket at the bore end?
Also, do you see evidence that the blade was shortened?

Shorter one could possibly be a US Model 1855 for the Springfield muskets?
