I think they only imported twice, but I read someplace they may import more this year. When I got my chicks the two lines where marked. Does someone have three lines?
Ps My sister-in-law lives in Calera, pretty lakes in AL. We try to visit once a year.
Sorry this is quite a few days after your post but have not been online for awhile due to job, etc.
I found out from Greenfire (Jenny) that they have three lines of Swedes- purple banded, un-banded, and pink banded. I have ordered some from the pink banded line recently, for purposes of avoiding in-breeding as much as possible (I have chickens from the other two lines right now).
As long as we are on the topic, does anyone else suspect possible "split wing" defects in their birds? I am going to wait until mine mature more to make any final determinations on that but gosh it looks like most have it- there is a distinct gap between the primary and secondary feathers, rather than a nice even fan. Hopefully it is because the birds are not yet fully developed. When I get a chance I will take some photos and show you what I mean.
Also, the rooster I really, really wanted to breed because of his deep red coloring and lovely straight toes turned out to have side sprigs (is that the correct term of art?) on his comb. I think someone else had that happen- maybe it was KYTinpusher. I am going to re-home him soon.

With the curved toes, the combs, and now possibly the wing issue- is this a result of inbreeding, and, if so, at what point should I/we consider out-crossing? Any experienced breeders out there please opine. I am reading what I can on the subject but not finding a good answer to that question so far.
Basically, I think this breed is the cat's meow- a backyard chicken-keeper's dream in terms of both looks and personality. I want to help improve it but not sure how to begin.
