Early 50's Gibson Dog Ear
I've had an old early 50's Gibson P-90 in my shop for repair recently & I don't think I've ever seen a vintage Gibson p-90 like this one . it's from an early 50's ES-125 dogear .
I've never seen a bobbin like this in an old p-90 pickup It's like it's made from a b/w/b 3 ply pickguard but it is pretty rigid .
Any one resemble this to one of there repairs ?

might have been rebuilt at some point

Interesting. Several questions come to mind.

What is the core material? It looks like it is glued together--Correct?

Are there counter-sunk holes for the adjustment screw heads? -- Hard to tell from the pics.

Are the inside bobbin dimensions consistent with other period P-90s?

Agree with Jack, could be a rebuild.

Here's a few more pics
The holes are not countersunk , the dimensions of the bobbin is similar to a vintage p-90
the core looks like it is attached with silicone but it is not as that white glue is quite hard .

That bobbin looks homemade to me. Maybe somebody sometime broke the bobbin sides out and replaced them with some leftover styrene sheet?

What does the coil/tape look like?

The tape looked like the Period correct tape black but it wasn't coming off easy

Looks real to me. I have an old Gibson P-90 with rod magnets with the bobbin made of the same material.

Its real- I have seen lots of them like that and pattern my P-90s after that with a built up bobbin.
They dont rot like the injection moulded ones

Thanks guys The bobbin is pretty much rock solid & not full of cracks like the later 50's bobbins .

This p-90 have that higher tpl of the P-90's that I've dissected but this pickup was machine wound with typical era wire & so i did not think i was rewound or home made bobbin .
