At my house today arrived a very nice condition 1992 Custom 24. As I unscrewed everything to check for originality (no expert though) I noticed that the bridge does indeed to be one of the original MIL-COM one-piece models. The bridge on my 1993 Standard 24 definitely has the three bolts; this looks to be one piece and has the "MIL-COM INC FRANKLIN NH" stamp.
Were these standard on later models? I thought they were only on the first couple of years...so maybe someone replaced this one? Thoughts?
