Tabs,
Who did translate that for you?
It says "To your birthday from" and then the six initials. This was given to someone for their birthday by 6 individuals, most likely from their comrades. The front inscribe MH or HM are the initials of the owner of course.
The word for birthday used is old fashioned and basically means "cradle celebration".
