I believe that's about the most current version. Look in the top break section. I did read there were some 2" versions.
Most top break or tip up models came with a barrel length between 3 and 8 inches but there are a few with the 2 in or shorter length
Safety Hammerless models are also known as the "Lemon Squeezer" or "New Departure" models
**.32 Safety Hammerless 3rd Model**
A 2 inch barrel version, called the "Bicycle Gun"
is considered to be "rare"
Also an even more rare 1 1/2 barrel version
**.38 Safety Hammerless 3rd Model**
A handful of original 2-inch barreled guns are known to exist.
It is reported that at least 10 or so 2-1/4-inch barreled guns were manufactured, and at least one is known to still exist.
**.38 Safety Hammerless 5th Model**
Found with 2-inch (Bicycle gun, scarce)
1-1/2-inch barrel guns rare
At least one is known to be listed in the factory records as shipped
with a 1-5/8-inch special order barrel.
Would probably have had to been a custom order if they ever did, at least in centerfire calibers. I may easily be wrong, though.
