I've been eyeballing this piece at the Wallace Collection for about seven years now. It's titled the same as this artwork's title; Combined axe and wheel-lock pistol with ramrod, it was made c. 1570 in Germany and can be found at this link: https://wallacelive.wallacecollection.org:443/eMP/eMuseumPlus?service=ExternalInterface&module=collection&objectId=61800&viewType=detailView
I'm very excited to have completed a recreation of it as my hero prop for term 2 of Think Tank. The asset is now game ready! You can view it here in real time through Marmoset. I'd like to one day animate it to fire and mod it into games. Also one day I hope I can get my hands on the real thing!
