Hey Del, Look what I found!!! An original Miller Gauge tester!!!

They may be using the "blue" resistor in parallel with the 22 ohm (red-red-bk)

If so, that would make the "blue" one somewhere around 18 ohms

17 ohms would be brown --violet-- black,

That would make the third band black. If we can figure out the first two bands

Showing the low resistance as 10
