Bell-Boeing V-22 Osprey 42113 | Technics | LEGO

It's important to clarify that the LEGO Technic 42113 Bell-Boeing V-22 Osprey set was never officially released for sale by LEGO.

Therefore, we can't accurately say it's "no longer on the shelves" in the traditional sense, as it was never on shelves to begin with. It's indeed exceptionally rare and unavailable through official channels because its production and distribution were halted before it reached the market. This makes it a unique item for collectors who might be interested in unreleased prototypes or cancelled products.

Due to its unreleased status, there are no official product details or descriptions to add to. Any information available would be from unofficial sources or prototypes.
