Thread: "Gun Metal" Wester Bros Bone - Any Info?

Picked these Westers up the other day, two 6/8 and a 3/8. Never heard of Gun Metal before, looks annodized/blued. Fourth picture is manganese, looks like it might be special with all the marks. The scales are bone, very nice bone in fact, not dried out or chipped or cracked, very stable. I'm not too attached to them, do you think they are worth selling? Anyone have any info on them?

Thanks in advance
