|My Carrillo's had a very distinct finish on them, I had never seen a similar finish on any other rod.
It is really hard to say, your best bet is trash them all together,
IMO it is just not worth the risk..
I think JE and Pauter also made rods for the VG at one point in time. You may source some photos for those.
I would say they are Ebay Key's (Junk)
