Jesus H. Christ, those are fucking gorgeous. Alden at its finest.
If Alden says it's Trubalance, it's Trubalance. Retailers don't always know what they're talking about (see, e.g., J.Crew's "Horween Chromexcel shell cordovan upper").
Plus, that stitch shape is always indicative of Trubalance. The last shape is also a giveaway - too rounded to be Barrie.
Alden is accepting GMTOs again?
Any limitations on the models and leathers?
It's more like a retailer is agreeing to submit a run of 12 pairs if they are committed. I don't think you can do them in any rare shells (I mean, you could if the retailer and Alden agreed, but it would be a very very long time for the order to come in). Most Alden shell runs are for 12-24 pair now. Some rare shell runs are only 6 pairs.
