I would have figured that, given the pricetag, LMT would be all about putting their name on stuff to say "Look at me, I'm designer." DD, BCM, Spike all do it. However, I can respect some quiet professionalism, but it does seem odd that there's no marks at all to identify who made it.
I suppose that's work for me, we stamp our name on everything at least once, along with part name and serial number. Hell, half the stuff we sell gets multiple sets of stamping at various phases of completion. Different industries I guess.
