Bergen Norway marks help needed

[Adam.NYC]

Hi all. I see the Bergen Norway 7 ball mark on these 4 spoons but I need help understanding the remaining marks. It looks like B MB H 20. Can you help? Thanks!

As you assume your spoons are made in Bergen. The marks:
Bergen town mark
MB is Michael Blytt, active 1816-1839
"H" is the zodiac mark for Pisces 19.2.-20.3
20 is 1820
