That rack of wands does seem to be identical, apart from the blue wand in the shop, which obviously isn’t in the castle.
It’d certainly make sense for Robin to be all, “I have some experience with fairy wands,” and somehow use that to help Neal get to NL.
Oh, new thought, I wonder if the blue wand was used somehow to send pregnant Marian to our world, and so Robin has some specific knowledge that could help with portal via wand?
