Help ID ING manufacturer

Took apart for cleaning and my 45 fell off and got damaged beyond repair. No tags on any of the pipe. Local dealers think it is either GSW or Security?
Hoping I don't need an entire pipe system.
Cheers,

Looks like Security Secure Black stovepipe. If so, their 6" elbow is part 6DE45.
