I was curious what are these brands and what would be an average someone would get these for?

I got these from an old friend of mine, and was curious what kind of brands would these be and how much would someone get these for? It's been forever since he got these, so I'm curious!

Thank you!

It's always difficult to know who has made individual tattoo machines unless the maker has engraved their name onto the frame somewhere. The top machine I have seen before, it was a chinese knockoff that was sold on ebay, it could have been an exact copy of this machine, this machine has metal parts instead of plastic, so could be the original machine that was copied. Having said that though, not many builders would use engraved coil covers on their machines....too hard to clean and I think these machines were made well before machine covers were started to be used. Maybe replace the tips in the grips....they've been used and look a bit grotty

On the grip it has a small skull, angel carved on it and behind the grip there's a ceaser with a shield carved on it, and I've been trying to use keywords to try and find at least a similar one, lol! Also yeah, I couldn't really find much carved coil covers so I do wonder when were these made.

Turn the machines over it's hard to see the brain from this angle but if you go by the hardware like the locking nuts for the tube their newer most likely cheap eBay knock offs
