My mother in law gave me an old cap gun.It says on it oldironside8.The barrell is about 8 inches long it is made of steel or cast iron don't know for sure but it is metal.She believes it is from the early 20's or 30's maybe even the 40's.I can take pic's and send them just wanting to know how old it was?Can someone help me out please let me know something?
Thanks.

Above is the Spy cap gun.

Last two are Old Ironside 8.
