Freddy, from and outdated source.
Namely the 25th editiin of Blue Book on Gun Values a 100% rated gun would go for $400.00
This would be in US $$ of course.
The gun would be a 1972-74 manufacture, 5 shot, 2/3 tube mag.,24 inch barrel open sight and pistol grip.
This is old out dated info.
Take it for what it is,was worth.
pg 1740 from the issue mentioned.
