My new Standard tank arrived Friday.

^Pulled it out of the box and made sure it had no fresh dents from its trip up here, but all was good. Some minor scuffs and marks as stated, but nothing I can't live with.

I knew it had no taps with it but didn't realise the cap was locked with no key supplied.

^ was just getting prepared to put a screwdriver in the lock to twist it open when i realised that the lock barrel had a number on it

^ as opposed to the Standard "push" as stamped into the normal tank lock. I'm thinking that maybe the lock centre had been taken out of a helmet lock, as that's the only place on my bike where a number is visible. Someone chime in if they can tell where the barrel mechanism would be the same as the cap. Tried my key in it, just in case the tumblers had been filed down creating a dummy lock, but no joy...................................

^ then I happened to glance up at my old Special tank, which has the lock mechanism out of my donor E model fitted to it. I pulled the key out and ..........................

^ couldn't believe my luck! Took my hopefully matching key over to the tank, inserted it and gently tried turning it ( it did appear that the cap hadn't been opened for a long time due to the dust down in the gaps each side of the flap).

^ You beauty! No surgery required after all.

^ I had been a bit concerned about the tanks condition when I'd asked the seller to post up a photo of the inside, but he didn't, so I was relieved to see that the inside was very healthy with only 1 tiny speck of faint surface rust to be seen through the filler hole.
Things happened very quickly from this point. Took Geoffs tank outside and drained it, removed the cap lock and fuel taps, refitted the taps to the new tank and swapped over the lock centre then fitted her up.
NOTE - All the spots in the 2 previous photos are actually particles of the foam packing in the box. (it's pretty old and crumbly, but it did its job!) Not marks on the paint or chrome.

^ Really looks the part now, though it didn't look too bad before with the bluish tank as a contrast

^ Shiny tank with gold lettering really makes my sidecover badges look like shit! After seeing a few badge refurb threads over the years, I have to have a go at prettying them up a bit (maybe another "how to" thread if they turn out alright).
