Tell me about antique spoons please!

For my last post of today of eclectic goodies of which I have no knowledge I present two spoons for your consideration. Both sadly silver plate but never mind.
I have a job lot of spoons to sell and want to make sure I note anything of interest if there is. Most are late 1800s/early 1900s and all plate except a little salt spoon.
The bigger shovelly spoon is 5.5 inches long and is made by K&D. Am I right in thinking Ker & Dunster which would put it mid 1700s or am I way off? What type of spoon is it?
The smaller one with the twisted handle is MH& co c1850?. Anything to describe this one or not of any interest?
Thanks for looking

 

The BP at the end of the K & D mark stands for Britannia Plate - mid 1800s' usage. No way it's 1700;s

 

MH and Co is Martin and Hall. https://www.925-1000.com/silverplate_M.html

1854 to 1934

 

Unfortunately I cannot find a firm name to go with the K & D mark.

 

Thanks for your help @Bakersgma
Do you know what the bigger spoon is designed for?

 

Might be sugar spoon, not individual size but for larger needs.

 

That makes sense as it’s quite big.
As you were then- nothing exciting!
