1984 is the second year he made them and production records according to ASPC vast archives....ok Mark's memory was about 18 pipes.
1983 was the first year and they made 6 or 7.
Originally I hadn't planned on trying to complete the set but I found a 1983 at the CORPS show in 1991. I showed it to Mark and he couldn't believe it. I rather quickly acquired a 1987 and 1986 and have been pretty much buying one each year as he's produced them.
After over 20 years I finally found a 1985 so now all I need is a 1984 and I'll have the whole set.
I know there is one out there somewhere, as you can tell, I'm trying to speed things up so I don't wait another 20 years.
P.S. There was a 92 at the CORP show but that's all I saw.
