Man this has to be an MO-4.5. Everything else matches except the veneers.
In looking into this cue, I have found a bunch of other MO-4.5 cues with veneers that are unique in color, etc. I believe it is a case of Meucci using whatever materials available at the time of the production run. I can't prove this right now, but I have reached out of a few of my contacts who would have been working at Meucci in that era. If they get back to me, I will let you know. The only support I have for this theory is the photos of supposed MO-4.5 cues below, all with variations in the veneers.
The catalog photos would have been done from prototypes or a first run in whatever year they debuted. Your cue, bought in 1987, was probably made with different supplies on a different production run, but still sold as a Meucci MO4.5.
The 84-4 shaft collar squares are offset from the squares on the cue's joint collar, so normally we could say that rules out the 84-4 from the 2nd edition, but since you had the shaft replaced, we can't be sure, unless you remember how the original shaft lines up.
Here are some of the other veneer combinations I have found (note, the people claimed them to be MO 4.5 cues, but they be misinformed, no way to know for sure):
And finally, just for comparison, here is an 84-4 from the 84 series first edition:
