I moved my post for a free HM 4.3 Thermocouple case over the buy, sell and trade forum. You can find the post here if you are interested:
I am building a HM for a friend and by mistake printed him a 4.3 Thermocouple case instead of the Thermistor case. I will drop it in a padded envelop and mail it out to anyone who needs a HM 4.3 Thermocouple case in the spirit of contributing what I can for this project. Just post a reply here...
