Thanks again Mike,
Then for fun, I looked for consecutive engine numbers to mine, Can't find any.
I guess engines could have ended up anywhere in the world.
And Mike you have better eyesight than me!
It is not a upside down W but as you said a 41.

"Anyone" ? What are these holders for ?
The vertical unit has this bottle in it, I suspect it should have a cork in the neck.
Old age equivalent to "Start you bastard" ?

And then I have found the reason for the leak in the water pump
The mice have eaten the cork out of the hole !!! (or maybe it just rotted away) Lucky I have managed to find a spare pump with an impeller and a fan no less.

And finally, What are these tanks for ?
They are different. Both have a pipe fitting on opposite sides.
These pipes are at differing heights. There is no other way of getting any substance (air/water/petrol) inside.
