Other weird things they did included using odd looking German resistors and or American made factory rejects where the marked value was wrong but the measured value was right...

Could I simply replace them with half the value? Or were they done that way for a reason?

I have an Admiral 26R12 that is identical to the one I had as a teenager. It has a rectangular all glass CRT. I restored it (even though it was working!) and during the restoration I found out from many of the members here and on the Antique Radio Forum that there was a component shortage possibly due to the Korean War Effort. I also found many paralleled resistors and thought that some idiot "Had been there".
So, what you are finding is OK; normal. I suspect that if the final value of the combination is correct, you can leave it. Heck, it is part of the set's history.
