From Kamar Figureen, a German seller. Link is in PSR, you can contact them via their website, they've got an online shop and you can pay with paypal. They're really nice and still have some rarer sets. Note that the "command sprue" of the Richelieu set is in grey plastic (as shown by PSR) the rest is in red. PSR also has only grey as color for the Musketeers, don't know if they were ever made in red, perhaps it's a confusion with the Ultima Ratio set?
