I recently bought one of those Corvette/Cortina catchers for the Waltons store brand I found on the side of the road early this year. It has a one inch crack starting on the lip at the bottom just under the metal tongue. I drilled a small hole at the end of the crack to stop it spreading further.
Ahh, if only victa had kept producing the thumblatch catcher series, they would be in better shape today!
