I have an eclectic firearms collection including a 1/3 model of one of Nelson's 24 pdrs, a copy of the Loshult Gun two doppelhackens that I will write up at some point, and two wall guns.  I also have a variety of post 1900 pistols and rifles.  I have a weakness for Lugers.  I will restrict my posts to the stuff from <1600.
I have a couple of models of Mons Meg and a really long and tedious story about an 1850's photography exhibition that featured a photo of a model of Mons Meg and where that self-same model is today.
