These are the same set of reedplates used to make he Delta Frost. A set comes already attached on the comb. Reedplates come in the 14 keys. Yes, we have them in stock and are ready to send them out. Bushman has allowed us to order directly from the factory, and has allowed us to order reedplates in all 14 keys. No one else is currently allowed to receicve reedplates. Except for a few sets of reedplates out there that are still in stock from three years ago, we are the only current source of reedplates. We can ship immediately.
