Yeah, I had communicated with him a few days back and he said he could get some in if there was interest. He'll probably keep them stocked if they are selling well.
Perhaps someone can weigh in, but as far as I can tell this is just the Leopold counterpart to the Ducky's that this thread is about, at least where 45G is concerned. I suspect there is no limited aspect about this, it's just using the old AE colourset due to it's popularity.
I decided to grab this because all costs considered, I'm not paying much more than the Ducky since I'm in Canada. Standard shipping is included with these Leopolds, but I'd have to pay shipping and likely tax for the Ducky... and I greatly prefer the blue/grey to all white caps.
I have no idea when it will actually come in, but if there aren't photos already on GH I'll put some up in the Topre thread. There's at least one other member on GH that already owns this from alternate means since he posted a quick photo.
