I think all of Jim's models are kits, and the Heuss is one that just caught his eye. He's got at least 4 more running models, maybe more, that he didn't bring that Sunday.
Macedonian isn't much more than a bare hull right now, the sailing warship model in the pictures is Constellation. I was going to bring Pride and Mac, but my car will only fit me and one model. I actually probably could have fit Mac in, but I was too caught up into stuffing Constellation in without snapping anything off, that it didn't occur to me.
