Not to hi-jack this but whats an LD340 worth?

Don @ FBO recomended a Performer RPM for the 360 he built me so my LD340 is collecting dust. Its had a long life I had to repair every hole on it by drilling it out and putting in metal inserts -not helicoles- And someone notched the center divider and decided to make it also fit a spread bore.
