These were in a box with some older heads I got.
Not sure who makes them or if they are even that old.

Looks like a vented Magnus 2 to me, but I can't say for sure since the only Magnus head I use is the Magnus1.
i think its magnus
I third magnus
Definitely Magnus.
Magnus II... ;)
Those are Magnus 5/16" glue ons, should be just under 100 grains for weight. They've been around for a while but are still current production.
Thanks guys !!
