Ordnance Department Automotive Materiel 1930

I apologize for the inconsistent posting the last couple of weeks. Hopefully this will make up for it; it's a special, very large document I've been saving for a while, that shows all (or most) Ordnance vehicles up until 1930. I will be posting an update on future plans soon.
