This is indeed FM (FÃ¤re-Marcolin) Konstglas Ronneby. I have seen two
different paperweights with the lion, M-78 and M-79. Yours look like M-78.
I have created an album on Webshots with the pictures I have of M-79. There
is also one picture showing both paperweights, taken from a FM catalogue
from the 1980's.
