I sold one a year or so back on here to a fellow in New Hampshire I think it was.I think I sold it for $250 and that included a new wood stock I made, a Williams peep sight, and scope bases peep.
The Black Diamond is an early inline.You cannot use BH209 powder in them.
Bill N is correct. FL not needed , advertise it, price it so it will sell, and send it of thru USPS.
For those interested here is what a BD looks like except they have a black plastic stock.
