you can still buy them mate google olt 800 goose call they come up on ebay in the usa mate
Olt went out of business around 5 years ago The Archie Jordan calls parts are made by a Guy called Dave Jackson who used to work for OLT. They are shipped to the UK and then tuned by Kevin Wilcox AKA Archie Jordan the main reason is David Jackson is a Master call maker but has never seen or heard a Pinkfoot or Greylag Goose.
Intersting point we have to retune the Canada calls as well as the US versions are too high pitched for the UK geese.
