Design and production by Derek for TADACT Productions.
This illustration is from the 1997 Catalog which explains the semi-commercial set-up.
I made the original model for this for TADACT and it proved very popular so we put it in the TADACTP Catalog. Orders poured in but no TAD volunteer wanted the commitment so I tooled up for it at my Burra workshop. Well over 500 were eventually made on a non-profit basis. I have one at home and use it every day.
