Dunno if those guys made the tank I had but I was happy enough with the one on my A. Threads good and in the right places, Cycle for the strap, BSP for fuel taps (plumbing ball valves went straight in, no slop no leaks), and knee rubbers & central hole lined up no problem, not bad chrome, bayonet cap fitted OK, served me best part of 10 years and still looked good even without being polished much (hardly ever). Not for purists - one man's happy can be another's 'appalled' - and I'm sure the shape wasn't perfect - but a better bet for me than a bodged-up original with sealant, braze and weld here and there etc etc. Good value too, and would go there again for any daily workhorse. In fact am probably going to have to before long on one of mine.
I raise my hat to the dexterity of the folk doing this stuff - without them, we'd be worse off, even if some of the bits are sub-standard. But would order through a reputable local reseller, not direct from India, as no comebacks doing it that way.
