I actually built one about a month ago, but haven't done any weathering yet. Mine's done in similar camo (I think a lot of people go for this scheme) but a bit lighter as my airbrush was being a turd that day.
I would like to pick up a gun crew for it - don't know why they couldn't include one like they did for the Sd.Kfz 7/2 Flakvierling kit.
If you don't already have them, you need to build a Wirbelwind and an Ostwind to go with this; they look good together on the shelf.
