Drum Brake Backing Plates REAR 10 inch for 1.75 brake shoes. SBP

Cleaned painted and bare.
Price for the PAIR is $50 plus shipping or a reasonable offer.
Located near DFW Texas
Link here to how I measured them : Can someone tell me what these backing plates fit?
I have a lip on my workbench, so the measurement is off about .1 inch.

I will TRADE them for a pair of 10 inch emergency brake levers, PIN type.
Please contact me if interested.
These did NOT come off the RMS Titanic Ocean Liner.
