Don't be paranoid about 'threatening' copyright issues. Sure, if you're pirating a major or commonly known/used logo FOR PROFIT you need to be careful.
On the other hand if you are using an old or more obscure logo FOR NON-PROFIT USAGE, don't worry too much. It's very rare to get into trouble doing that, and besides, the first thing that happens is you get a 'Cease and Desist' letter, so you can simply cease usage at that point if you feel it's a worry, and it goes no further.
The 'BSA Company Limited' appears to be held by a British company, Boy Scouts (America)? is just being pushy IMHO, that's just bullshitting, just go to another printer.
Do you think that the scouts could own international copyright to a particular combination of 3 letters of the alphabet?!
If you think I'm 'slack' on copyright issues, bear in mind that plenty of my graphic work has been copied over the years, - you just have to accept that you don't have the resources to chase 'em and sue them... relax, "imitation is the sincerest form of flattery".
I know I opened my big trap regarding the design, and I will work on it, but I'll need time. As I see it a logo would be really useful, but it doesn't mean we can't have designs like the cutaway image and GF photo image, the idea is that the logo would be integrated into the design as a sort of 'key-graphic' or 'header'.
