Firearm engraving based tattoo?

Curious if anyone has seen or has a firearm engraving type tattoo?
I'd think English Rose and Scrolls or German high relief engraving styles could be used the same way various tribal styles are used.

I'm getting my back finished soon. Gotta do some finishing touches like filigree around the longhorn skull and I'm gonna have my buddy "engrave" the guns. I'll post up how it turns out.
