Len,
Please re-read my message. The "special" sleeved thermo is a
Robertshaw with an extra sleeve soldered to the existing one.
I removed the sleeve from the 160 thermo and soldered it to a
180deg Robertshaw ... presto, a "special sleeved" 180deg thermo.
I'm in San Jose ... if you get down this way stop by and I'll show you
the two thermos, and the extra sleeve.
