Outlaw Country Legend's 1979 Martin Custom Shop 000-18

I bought this recordable Martin from Jerry Jeff Walker in 2005, one of his studio guitars. I have a handwritten and signed Bill of Sale. I also have a statement on letterhead from a musician who toured with JJW and helped me contact and purchase the guitar. It has a pickup and is mic'd with a volume wheel.. Comes with a period hardshell case. I never thought about selling it - I have an opportunity to start a new business - why for the sale. This isn't a fire sale. Great warmth and tone. Purchaser must come to Austin for pickup as I will not ship. To protect both of us the transaction will take place at my bank here in Austin and must be in cash.
