I've started on my 40mm collection re-vamp, firstly I converted some artillery crew from tricorne wearers to a sort of furry grenadier hat - these will end up as Freikorps artillery.
Next I made up a list of all the units existing and planned, then did a list of all the items I had to cast, then embarked on a couple of long sessions of casting (just had enough metal for what I wanted to do); the gaming table got used as my workshop ....
One result of all my casting, a new grenadier battalion using the new Prince August prussian moulds.
I found the new PA moulds for the prussian infantry easy to use, giving good results - occasionally a little trouble getting the separate heads to cast.
