Parker 214991 was shown to be a VHE 16 (ejector gun). Do the replacement barrels have ejectors and if so do they work?
The original barrels were 26" according to the book, so if your set is a different length then perhaps a second set was added. But unless damaged, there would have been no reason to replace good VHE barrels except for another set.
Perhaps your originals are out there somewhere, or deposited in a landfill by someone cleaning out after an old timer passed on.
There is a thread where people can post for missing parts of guns. A one in 241,788 chance.
