OAL 1 3/4" This is a Little Atom Squared Butt with checkered design on the grips, the similar Austrian version does not have the checkering and has a floral background. Marked: JAPAN on one side, this is a later version with the barrel vented on the bottom, meaning that it can only fire 2mm Pinfire Blanks. This one has a rounded hammer that is hard to lock back but the trigger is crisp. The gun looks good for its age and only has some minor scratches and wear. This gun is in good working condition and is in (A) condition.
This is listed as J3a in "The Tiniest Guns" by Bob Urso.
This is a vented barrel, which means the barrel does not go all the way through/is sealed at the end, which meanonly blank rounds can fire safely. It is dangerous to attempt to fire any kind of live round in a vented barrel gun, such as this. However you can fire blank rounds perfectly.
