Our catalog record ties this one to appearances across 1969–1970, but we don't have anything more specific than that on file. If you're matching this to a particular tank or trying to figure out if your cap is the correct one for your setup, give us a call and we'll help confirm before you order.
Beyond that, there's not much else to add — the catalog entry is brief and the description doesn't go into thread specs, material, or finish, so we're not going to guess at any of that here.
We've never carried this one. Tell us what you're after and we'll go looking — you'll get a price and photos before you commit to anything.
