I hope you post pictures. Considering the Beagle one can remove the name and call it something else. Just not the Beagle.I get a lot of satisfaction with taking the few plastic kits available and making the corrections and modifications necessary to make them serious models. For example, I am currently working on the old Revell 1/96 CSS Alabama in which I have relocated gun ports, made surgical alterations to the hull to make it more accurate, and am scratch building the deck furniture because the kit parts are so inaccurate. I have replaced the guns as well, and have taken the necessary steps to provide an eight degree rake to the masts. When I am done, I will have a much more accurate CSS Alabama than the kit provides. It will be more than simply being a clone of their USS Kearsarge.
The Bounty can be an excellent kit! But, its clone, Revell's HMS Beagle is a fraud. It does not represent that ship in the slightest.
Anyway, that is my soapbox, for what it's worth.
