Small nickel-iron temp probe needed

Perhaps someone has recollections of small assemblies of resistance wire
either used for heating, in the 10 to 12 Watt (at 120 VAC) range, or
for sensing, that might come in at around 1150 ohms, so that I might
avoid a tedious winding of hair-fine wire under magnification.
Michael-
Look for a 5 or 10 watt, 1200 Ohm wire wound resistor at Radio Shack.
Perhaps its temperature coefficient would not be what you need, but it
would give you a point of reference.
I wonder if a very old wire wound resistor from someone's junk box,
would be more like what you need?
