Could be. It looks like the ones in my 82 V, you be the judge. I have a feeling that most of the Shaw pick ups had brass screws and yours look like they are made out of steel but that is the only thing that I can see that looks out of place. All of the Shaw pick ups that have short legs seem to have those double rows of screw holes on the backplate. I assume that you know last three digits are the date of manufacture.
No, I did not know the last 3 digits were the date of the pickups. So 281 dates this one to February 1981 -- or is it 1991?
Based on the serial number of 96750---, this is a 1990 model, but the original pickups have apparently been replaced. The neck pickup is an Original Bill Lawrence, the kind with 4 wires and the printed circuitboard on the bottom (see photo). I have no idea how to date those, but thought they were mainly used in the 1980s. If this guitar is dated 1981, then apparently somebody put older (and better) pickups in this guitar.
It's a mystery guitar, to say the least. it has the unusual side jack, like a Les Paul, and most people say Gibson stopped doing that around 1986 or 1987. And yet, here it is in a 1990 model.
for the Shaw pickup, I would direct you to the Norlin subsection. They know their stuff
BL were '80s, but late '80s, '88-'90 or '91 roughly, so I'd guess that neck pickup is stock and the shaw was swapped in. I'd be curious what it measures and what the pot cavity looks like (i.e. soldering/pots).
It is a Shaw...you can see the white spacer through the holes......you said yourself that the pups are not original.
The early Shaw’s used the dirty finger base plates because Tim actually wound the dirty fingers FIRST, before the “PAF” winds....he used the base plates he had already been working with....the short legs are to fit the SG routes etc...just makes sense production and Money wise.
the Screws look like brass to me, but regardless.....
February of 81 would be almost a year into the Shaw run....
