Modern carbon film flameproofs are a good sub for carbons.
Sams manuals as a rule just list carbons by value. Other special resistors
they give specs & OEM part numbers.

I agree with your advice as to using the same component as was originally in the set. The manufacturer had a good reason for using the values originally installed in the chassis; the use of other parts can cause problems. In fact, it is very important to replace resistors, for example, with identical components; resistors are often used to drop voltages, and some, as you mentioned, are used as fuses, as they are designed to open under severe current overload conditions--not unlike fusible resistors in older, tube-type TVs. Replacing such a resistor with a standard carbon one could cause more damage than was originally done when the original part failed, particularly if the original resistor was meant to open in case of an overload or short.
