John,
Looks like yours is one of the 30/85/110C gauges that Randall mentioned (and
according to the "Original Triumph" were installed on the capillary equipped
cars). You mentioned that your temperature normally ran about two thirds
the way up the gauge. Based on your test results, I'd guess that would put
you in the 170-175C range, but I don't know how much effect on the
temperature reading the neck extension has (like you I would suspect it to
perhaps be a little cooler than gauge temperature, but certainly not as
drastic as you've recorded).
Your gauge seems to be off in the opposite direction of mine... However, the
markings on your gauge seem to make a lot more sense than mine. :)
