Aviv,

Very good points. I do not know what the situation is as to "delay" on
seeking royalties (I suspect that Lockheed is out of luck if it tries
to get them for plastic models of the P-38), and failing to insist on
one's rights for a long period of time is often fatal to the claim.

I also agree that it seems pretty petty on the part of Boeing and
Lockheed Martin, but then again, I have no idea of the size of the
model aircraft market. (I sure put a heck of lot of my allowance money
into it many years back g.)

All the best,
Rick
