Sterling Silver Spoon Identification Help?

[startrekfrontier]

I recently acquired a few silver spoons, and have been trying to ID them, with limited success.

2 appear to be late 19th, early 20th century items. 

One has a 'H' in a circle that I cannot find referenced anywhere.

The other is a spoon that is older, appears to be either Coin or Sterling silver.

The Hallmark is an Arm & Hammer, a Crown and Lion. I've included photos for reference.

Does anyone recognize the makers?

Thank You in advance!

the one marked with the H is by Gorham (lion, anchor, G)

The last picture shows what looks like a coin silver spoon maybe 1830s-to 1860s. This would be about 800  or 80% silver. If the spoon is thin and light it's coin. Otherwise, it 's silver plated if heavy and thick. The lion and crown sounds British. There are books on coin silver makers. I don't think it's American because most American coin silver has the name of the maker.

Yes, and the pattern is "Cambridge":

I noticed you upvoted one of my old posts from 2019, and now I see that it's the same mark as yours (Philo Dubois). Well done for tracking it down, I'd completely forgotten about it:
