Larry, other than the one conversation with Andy, I've never dealt with him. He was quite insistent when he claimed to have the rights to the Lefever name.
I know Steve Lamboy quite well and wouldn't be surprised if you are correct. However, Andy disputed this. Since there was more than one iteration of Lefever, they both may have had some interest in the name.
If Steve said he had the rights, I'm sure he did.
