28 gauge

[Thomas Cravey]

I own a 28 gauge 2 barrel set. Q1/Q2 26" and M/F 28 " barrels, pistol grip,single trigger and beavertail forearm. I have with this gun for several years and have taken everything from doves to goose.
In 2022 I had a house fire. The gun was stored in the factory case and in a Liberty gun safe. The morning after the fire the firemen pried open the safe. The canvas cover was burned and the case was covered in black smoke damage. I was surprised that the gun only suffered damage to the finish on the stock and case colors on the receiver.
I had the gun restored with new case colors and new finish on the stock and forearm.
While the gunsmith was working on the receiver he discovered that it was cracked on both sides.
Has anyone heard of any receiver cracking?
