This might be the first Seagull Doubleneck in 74 ~75. The following is Neal's message about Seagull's history.

There were 16 Seagulls at BC Rich when I got there. They were made in late 1973. Bernie told me he took 4 Seagulls to the 1974 Winter NAMM held in January at the Disneyland Hotel in Orange County, California.
When I got to BC Rich with the new electronic design in the early part of 1974 I modified the rest of the Seagulls to my design.

After those 16 Seagulls were finished we started with Seagull #1 with my new electronic design.
Seagull #1 was owned by Eddie Estrada who was a friend of Bernies.
Seagull #2 is mine. It has special electronics that I didn't put in other Seagulls. It also has special Inlay which I did myself.

And below is the Shop's comment.

Neal Moser Confirmed that he personally hand wired and worked on the guitar before it shipped. The Pickups are Gibson "T" bobbins and are 100% original, Moser used these pickups before he switched to Guild pickups in late 75'. All solder joints are untouched, A stunning example of BC Rich's early active electronics Innovations.
Guitar is in excellent condition and original. "Pro" headstock repair does not effect performance and is easily offset by it's rarity, exceptional resonance and playability. This double neck is truly a historical example BC Rich's first years of production.

I think the headstock repair had done in woodshop at B.C.Rich before shipping. There are no "crashed" damage on this guitar.
