I got a collection of small engine manuals on ebay the other day, bought for the diesel stuff. Among them is an 'Operators handbook for Charging set BD-12-C
250 Watts 230V AC 250Watts 12/15V DC'
Not my scene, if anyone here wants to make me a derisory offer for it they can probably have it. It's fairly tidy, but been folded in half.
Cheers Tim
