A different signature for Finn Jensen Norway?

[muraille]

Did Finn Jensen ever sign his work with the actual initials FJ as on this pin, or is it another maker? If so, who?
Thank you for your help. Link to bigger pic of the back: http://tinypic.com/r/wgp8o2/6

Hello
Yes, Finn Jensen also used FJ. This pin is his, I know it very well.

Tosten, thank you so much - I am very happy that it is by Finn Jensen. Does the use of the initials indicate a certain period or was it concurrent with the triangular version?

I don't know, but I can guess.
He started up in 1952 and I think he used the initials.
The mark to Finn Jensen was public registrated in 1963. I think he used it before that.
So somethimes between 1952 and 1963 he used both. I am not sure that I have seen the initials in my time (after 1965).
