The No.1 Colt Deringer is sometimes also called the National model after Colt bought out Brooklyn's National Arms Co. in 1870 whose No.1 and No.2 models were rated amongst the best concealable pistols on the market. The No.1 was an all metal deringer, the No.2 being fitted with wooden grips. All the unsold stock from National was moved to Colt's factory at Hartford, where Colt continued to manufacture the No.1 and No.2 models, later producing his own No.1 and 2 models carrying his firm's name. The use of the term National should really be applied only to those No.1 and 2s carrying that firm's stampings.
There were 6,500 No.1s produced between 1870-1890, and 9,000 No.2s, each series being individually serialised.
