I don't think there's any doubt in the cocktail community that it is sweet vermouth. Cool pic though.....is that yours?!
There is debate on the equivance of those measures -- I forget, there is a book that is an explication of the original Jerry Thomas, and also David Wondrich's Vintage Spirits and Forgotten Cocktails has some explanation of the measures. When I get back home, I'll post my recipe.
As for shaking v. stirring, the generally-accepted rule is that drinks with juice are shaken, while drinks with only spirits and modifiers are stirred (the idea being that you preserve the silken density of pure spirits by not mixing them with the shards of ice that shaking creates). I really, really, really, agree with this rule.
I use Luxardo, too, though I've tried a few others.
Tuxedo #2. I really, really, like this cocktail.
I feel you on hectic! Hell, shit, *^%, son of a &UE%$&.
Also, I applaud you for not using Rose's! That is way more work than what I go through, to make what is basically Lime simple.
Well, it's hardly drinking per se, but I was sampling my bitters collection. The only dud is the Aztec chocolate bitters, which I ding for having artificial flavoring. What do I want that for? VTR bitters are my favorite aromatic bitters, and though I just got the Angustura Orange, I think I am really going to enjoy it.
