Hi Curt,
Chuck Schwark has posted some good photos showing comparative sizes of old resistors in another forum. Here is his photo showing sizes of older dogbone resistors:

And here is another photo showing sizes of metal-capped dogbone resistors:

Hope this helps.

:I was wondering? I reallize that the old resistors were much bigger than the new ones I mean diameter and lenght I am wondering what size in watts were generally used back then the radio I have is an 1931 rca model 7 superrette. the resistors size wise look like ten watt resistors I I would like to know if 2watt would be alright to use.
