It might be of interest to you, my local RFD has about 20 air tanks being retested 3,4,7,9,12lt which will be back next week and I think the price will be good. I have my name on a 12lt so if you want keeping in the loop, let me know by pm.

Thanks for the heads up Phil. I've got a 7ltr one myself.
It's my mate that wants one. Going to pick one up from Macclesfield later today. Got it for £90 with 2.5 years test on it
