The Handley-Page Hampden of Virtavia comes in a new version and appears in different products at simMarket.
In the FSX product, you get all models and liveries at once, and it’s also compatible with FSX:SE. Owners of the previous version receive the update for free.
If you only have FSX Steam Edition, then you can buy the base pack that comes with just one model and livery (B.Mk.1, 185 Sqn., Cottesmore, 1939). Then it can be completed with the DLC product (with 5 models and liveries more, to make it as complete as the FSX product).
