I just got one and have no use for it. It is doubleblack and has a few scuffs. I'm thinking $50 but I'm open to offers or trades. I can make a pic if needed.
look at the number of holes on the mounting legs. Unless it's been drilled for extra holes a std spaced bucker should only have one hole per leg. Trembuckershave three if I'm not mistaken.
I'm gonna say it's a standard. It only has 1 mounting hole per side on the mounting legs. It has also had 2 nuts tacked under the holes to secure the mounting bolt.
