Hi and welcome to the site.
That is a great pump, very desirable. The value all depends on the condition and especially if it still retains the top, but Jack Sims book (1st Ed) places the value about $1100. Keep in mind that this is just a guide. As Dave said, parts are available but it gets pricey if the pump needs a lot of parts. Good looking pump.
Stay in touch here, don't be afraid to ask questions and post pics when you get your pump.
