I picked up a couple packs of infantry of both British and Germans and they are quite nice figures: A good array of poses in the packs instead of the stiff “firing range” you sometimes get. You even get men manipulating the bolt action on their rifles which is not a common pose in minis.
Height and bulk wise they are a little shorter than Blue Moon or Khurasan WW1.
I dont have any Peter Pig on hand to compare to, but I’d say they are a tiny bit bulkier. Nothing I’d let discourage you.
In an email they said they were looking to expand the ranges if they are successful, so a good time to get in some orders. I had no issues at all with either of my orders.
