Andy, that Hasegawa kit was first tooled in the 60's, then retooled in '89. If it has a RHAG hook at the back then you've got the retooled version, but it still has accuracy faults. The sad news is that there isn't a decent 1/72nd lightning kit, though yours can be crosskitted with an Airfix kit to make an F Mk 1. The Airfix 1/48th Lightning kits aren't too bad, & there are lots of extra bits you can buy to make a really good model, it'll cost you though.
If you want a really good a/c model mag, look up sampublications on the net, Scale Aviation Modeller International is probably Englands best seller, huge range of subjects & good, honest reviews, plus adverts for good suppliers. International subscription shouldn't be too bad.
Hey, don't stop whinging, it keeps it lively on here! (plus i work with Aussies, No worries!)
There are some good kits coming out of Eastern Europe nowadays, you'll probably have to mailorder though. Try wonderland models in Edinburgh, Scotland.
Do beware of East Europe reissues of Frog kits, the price is a clue usually. Though having said that, I've had fun updating a few, it costs little & tests your skills. In fact, if you're a bit rusty it could be a good idea.
Keep the questions coming, email me if you wish.
