It was a little grubby


But a quick clean up and it was looking great.

I took it apart and checked the inside of the cylinder and it was spotless. Must have been a good landlord. Well done sir!!
(Sorry I forgot to take a photo of that bit)
I got a set of sparklers and thought I would give each one a test in the interests of science you understand. All pints were from my rapidly diminishing barrel of Exmoor Gold.
Firstly the white sparkler:

Then the black sparkler:

And finally the green sparkler:

I forgot to take the photo of no sparkler at all, too many pints under by that point.
I've got a check valve in the post so that will soon be rigged up so that I can connect the pump to my corny keg. I suppose I'll have to do some more exhaustive testing when that is set-up too.
Oh well!!
