Just got another shipment from eBay last night, so now Brittany has "her" heavy stubber.
It's off of a Shadowsword, so it's rather large and impressive. I ended up using a Marauder arm, and a CSM arm with no shoulder pad. I ran some thin chain so it appears to be an armored arm like Gladiators used to wear. Looks pretty good. Pics to come eventually.
I will be gone all weekend, so the next time I will be able to update this will be next week, hopefully I'll make some progress in between.
