P90 Soapbar Pickup - Removed from a Japanese-made History guitar

This is a pickup, model SP-90, from Shimamura Music's original brand history.

Since history is a high-end brand, this pickup may have been specially developed for it, but details are unknown as no information could be found through research.

The guitar it was mounted on is a Coolz zlj-10, also a Shimamura Music original brand.
(Catalog specifications are included at the end of the images)

Sound output has been confirmed, and resistance was measured without any issues.
The magnet is ceramic, but it does not give the impression of a cold sound often mentioned, and I found it to have a rich, good tone. (Subjective opinion)

The lead wires measure approximately:
Longer one: 28 cm
Shorter one: 21 cm

This is a used item, checked and researched by an amateur.
Please refrain from purchasing if you are sensitive.
