A Talkbass‘er pointed out a New York Craigslist posting for a Guild Starfire modified by luthier Doug Irwin. Irwin worked for Alembic and modified/repaired/built guitars for Jerry Garcia. According to the seller, this bass was custom ordered by a Phil Lesh  fan:

Listing is for a Guild Starfire Bass that was customised by Doug Irwin, a former Alembic luthier who built some of Jerry Garcia’s most famous Guitars. I bought the bass in 1980 from the original owner, a pro bass player in the bay area. He met Phil Lesh at a SanFran party in the mid ’70’s and told Phil how much he liked his alembicised Guild Starfire. Phil gave him Irwin’s number and after getting Irwin’s OK he went out and bought a mahogany Starfire like Phil’s for the project. Since he played an early ’60’s Fender Precision he had Irwin install a wide, flat, 34 inch scale neck. Bass is in excellent condition and is unchanged from the day it left Irwin’s shop, with Bartolini Hi-A’s, Schaller tuners, a custom made bridge and tailpiece.

I emailed the seller, who provided me with full-size shots of the bass. Check it out:

What’s most interesting about this bass is the 34″ scale, Precision Bass-width neck. If you look at the 2nd image above (of the back of the bass), you can see the extra width because the neck heel is narrower than the rest of the neck.

If you’re interested, the seller can be reached via the original Craigslist ad.
