Nice plier! I got two different sizes of them. Interesting design. They disapeared from the catalogues in the beginning of the 1960s. They were replaced by better models.
The older pliers are marked with F.E. Lindström Eskilstuna Sweden, then Lindström Eskilstuna Sweden and last Lindström Sweden.
There is versions of all of them.
Could it be, F.E. Lindström? The companys name was that from the beginning, after the founder, F is for Frans and E is for Edward, it was the founders first and second name. The dot in a cirkle is unknown to me, maybe a ownersmark of some kind.
I got a bunch of those pliers, and they are interesting, it seems like there were atleast two producers of them, but nobody seems to know who. There is other types of this "simpel" plier, endcutters and sidecutters.
