Picked up a very clean Iver Johnson Pony .380 . Box and all paper work says Iver Johnson . Gun is Blue . On slide it says AMAC Jacksonville , Ark. Pony . On Owners Manual it has AMAC PO .380 . I tryed to find out some information on this gun , but not much luck . What is the difference in to PO .380 and the X300 ? What is a rough value at 98+ ? Thx. for any info .
