How many Gibbs GTS versions are there?

I have seen the following mentioned on this site:
* GTS-7/8
* GTS-1 1/2
* GTS-2
* GTS-3
* GTS-3 3/4

Is this the complete list? Any others? I'd like to build the whole family of them between now and Spring.

Merry Christmas.

That I am not sure of. Peter, Vineyardblues, probably has them all in original boxes so hopefully he will chime in.
