I need to know the condition of the pistol to give you an estimate of value.
It has a some wear on the edges of metal, also leaks a little in the brass valve cartridge.
The 79G was made between 1971-80. It's worth in "Good" condition somewhere between $60-$85. In Very Good condition it is worth between $85-$100 (But this one leaks).
Add 50% if you have the original box, add 25% if it has the adj trigger (Early Version) The 79G is modeled after the S&W model 41 firearm.
The original price was around $53.50.
No such model number.
