I have some LT 13s, but I’ve done bad things to them, so they’d be no good to you.
I did, however, see an LT 13 on ebay recently. I am none too impressed at Mithril putting them out of production, though. Sold out? Right when they’d made newer ones representing an army? Nonsense. When you get army figures, you want as many of them as possible.
I presume the LT Dunlendings will be next to disappear, damnit.
