It was an unusual recall in that dealers actually had to pay for the supply of bushings they sent us to correct their problem. Only $1 each piece, but pretty chintzy of them for a part that they wanted installed because of a self-admitted "potentially hazardous" situation if the seat moved out of position.
Once we installed one in a regulator and sent them the information on owner and serial number, they then generously paid us the princely sum of $4.00. A huge margin of $3.00 for our time! All that big money $$ for just an hour spent placating the owner, testing the regulator, installing the bushing, and then re-testing the reg and filling out the form to send to USD!
They rationalized by telling us it was a terrific opportunity for us to get divers into the store for more sales. I have to admit that really was a good opportunity to keep a customer happy and promptly take care of their reg while they waited. I don't remember any of them being grouchy about having to bring their reg in, and mostly they were pleased to have the service quickly performed. Turned out ok for us too.
I particularly like the Calypso-J, and still have three different models. The reserve really helped sell them in the early 70's before gauges became popular.
The older I get the better I was.
