Nice range - looks late 50's to me, MOL. Saw a TOL 1959 Westy 30" range about 4 years ago. VERY cool looking but was rode hard and put away wet, so I left it in the basement I found it in.
What is the diameter of the hole on the tub vs. the OD of the groove in the hose from the parts supplier? Give them a call and ask them to verify before spending money.
Nice boot, but I'm impressed by the sheen I see on that tub. You've got a nice Westy there. I like the look of those much better than the earlier L5 I found last fall.
