Rider 6-36 A-K radio Model 545 example R-14 & R-2 read 1 & R15 .25, all have upside down ohms symbols. What are there values??

Bob,
The symbol represents megaohms.

Thanks; thats what I was thinking

I had never hear that. I have always known it in modern electronics as mhos (1/ohms):

I had never hear that used for megohms, but notations are sometimes different in vintage electronics. I have always known it in modern electronics as mhos (1/ohms):

Another tip is: 'M' used to stand for x1000 (Roman numeral for one thousand), but now 'K'(kilo) is x1000 and 'M'(meg) is x1000000.
Not to get off-topic but capacitor value expressions have also changed. I never had nanoFarads growing up and it seems to be the standard measurement now. The new 3-digit nomenclature, the 3rd digit is the decimal placement (like scientific notation). i.e.: .001uF = 1nF = 1000pF = '102'

Good points, Walter. I still prefer not to use nanoFarads (nF), since micro- and pico- are more commonly used. I think they started using nano- to reduce the # of zeros in some cases.
