Many apologies John
seems that Alwyn did have the wrong number .
his secretary must have jotted it down wrong or something and he continued phoning that number.
he called your posted number from above post ..and you called back strait away.
so top marks to you .
like i said ...very impressed with the quality of the sino dro that you sell . I know it's not your fault...but If they got the manual right and clear ... I would have two systems off you right away .
all the best.markj
