They don’t sell this pickup separately?That's a J-160E. Gibson created their own pickup to install at the factory; it was different from any of their standard electric pickups at the time.
Any luthier should be able to install an electric pickup like that, but it does require cutting an irreversible hole (or six) in the top.
Harmony never wound their own pickups although Gibson may have supplied them with parts to assemble them. That is the reason Harmony relied as heavily as they did on Dearmond-Rowe.The P-13 was not given to Harmony; the tooling to make it was sold to them. Harmony did not incorporate Gibson-built pickups into their guitars.
The National 1155E did not incorporate a P-90 because Valco made their own pickups - indeed, they built the entire neck on that model including the pickup.
Oh, but they did wind their own. They did in the '30s and '40s before they ever used DeArmonds. They then wound P-13s into the 1960s. Gibson had stopped building them by 1946 (probably more like 1942) and sold them the jigs and dies for machining cores and stamping covers.Harmony never wound their own pickups although Gibson may have supplied them with parts to assemble them.

As a start, as far as I know Harmony did not produce any guitars with pickups until possibly the very end of the 1930s. They first appear in the 1940 Sears (under the Supertone name) and Harmony catalogs which show one lap steel and one jazzbox. The pickups were huge three coil affairs. Who produced them though I do not have a clue.Oh, but they did wind their own. They did in the '30s and '40s before they ever used DeArmonds. They then wound P-13s into the 1960s.

Those Supertones appeared in a 1936 Sears catalog (I think it was late that year, maybe a Christmas edition):As a start, as far as I know Harmony did not produce any guitars with pickups until possibly the very end of the 1930s.

Harmony did not start mass producing guitars with pickups until 1947 such as the H50 and H51 which sported pickups they labeled "Tone Emphasizers". Francois Demont among others always referred to the pickups as Gibson P13s. The luthier who worked on my H40 described it as a Gibson lap steel P13 with the "speed bump" cover plate removed. But that does not preclude Harmony having built them with the original Gibson tooling. It would be nice if somebody could produce the contract for suppling pickups or parts or if not some kind of documentation for sale of the tooling.
