I appreciate the help John, and I love your spotlessly clean chassis!
Mine has a lovely coating of surface rust and peeling paint everywhere!
Anyway, your advise made perfect sense to me when I was under the car today. It was of great help.
I found that the two wheel cylinders were seized to the back plate. I freed these up so that they now slide back and forth used my hand. I also found that the automatic adjuster lever is broken off in the passenger side hub. I will get one ordered.
I adjusted the handbrake like to said by screwing out the automatic adjuster wheel and fitting and removing the hub. It worked a treat.
