I'd be interested to know why exactly Revell Germany decided to remove HMS Bluebell from the 1/72 corvette kit's instructions and decal sheet (all the kit parts are still there!). The UK is a major part of Revell AG's market, and the kit sells well here (especially to R/C modellers); it's a shame British modellers can't build it out-of-the-box as a ship of their own navy!
When I built the kit as HMS Bluebell I used some spare aircraft decals for the "K80" on the hull.
I haven't seen Bob Pearson's decals before; I've got another corvette kit which I intend to build one day as another ship, so will definitely use these if they're still available then!
