tv show swat walkie talkies

These are from the T.V. show SWAT in the mid 70's.
I have seen a truck in a few places that had a 40 channel C.B. in it but I cannot find any reference or picture for these anywhere. they are in the original box and it still has the warranty card inside. I do some buying and selling of things from estate sales and buy some unusual items sometimes. I only bought these because I am a ham radio operator and neat old things like this are cool to me. I wonder how many of these were made and how many are still in existence since I cannot find them anywhere, and I am pretty good at finding things.
