I took the second post at face value as I couldn’t make out the last number of the serial. Having made the reasonable assumption that post #2 quoted the correct serial I spent a good couple of hours hunting around the web for any info I could find on SL569.

In my book that doesn’t justify tagging me as lazy.
I did my best to help out another forum member but if that is going to mean that I get insulted for my efforts I just won’t bother in future so, like a lot of others before me, I am outta here..
