Hi Darryl,
At the risk of hijacking Stuart’s thread:
Occasionally you see something that you say to yourself - why didn’t they do that originally/ why didn’t I think of that! ?
I have found that this is area is very cluttered and this would be “one more bit of tin to catch dirt/ get in the way” but it stops the inadvertent foot kicking the battery, so Yes, I’d be very interested to see how it was attached, if you would not mind posting for others to see or PM me if you prefer.
For the uninitiated, rust in these boxes = Caveat Emptor - (just pointing it out as I’ve been caught before.)
