Hi Miriam
I'm not 100% sure - I met your brother and dad for the first time at 2010 IWA, but we made the deal at IWA in March 2011, but we ended up moving to Canada in Sept 2011. I live in Calgary.
Sure is a small world. And yes, great products - I got introduced to Tesro by a friend (an investment banker in London at the time) - Peter Dragomer - who asked me to talk to your dad about making a 12ft lb version to be used in Field Target. I was also a field target shooter, and was a member of the South African Protea team. I just never got it all to work, as we decided to move to Canada only a month after 2011 IWA.
