Lambretta GP build thread

As some of you may know I've recently decided to take the challenge of restoring a GP starting with just a frame. I've never done this before apart from rebuilding a few pit bikes here and there. I have a few good sources in my local area which specialise in just scooter parts which is pretty lucky i guess. Anyway after a week of waiting my italian gp frame came today in the post and here it is....
I will be trying to buy as many italian parts as my budget allows but will have to make do with some indian bits i expect,
will be asking a lot of questions on here as I'm a complete noddy when it comes to things like this so thank you for putting up with me in advance

May I make a suggestion? Whilst you have it in this state and before you get immersed in the endless search for all the other parts, get the frame on a jig to check whether it is straight
Please don't assume that just because it looks ok, it is. Trust me, I rode around on an Italian GP frame for 4 years before getting the frame checked out. To say it was unsafe is an understatement.

Wise words. Its probably fine but a few quid spent now could save a fortune and a lot of work later on.
If the frame is from a UK bike, I'd also check that it hasn't been registered as stolen at some point. I'm not suggesting that whoever you got it from is dodgy but a lot can happen in 40 years. It would be a heartbreaker to have the thing seized by the police because it was reported stolen 25 years ago when you try and register it.

I'm assuming it won't be ready for our rideout this weekend lol !
I've also said before, check the frame because once one part fails to fit, the rest get progressively further out.

Bought some shiny bits today, had a quick look at all the bits earlier before i went to work and a quick browse in the haynes manual (the pictures aren't great in there as a guide but I'm sure ill work it out). Also i think the spring is going to be a lot of "fun" to fit judging how stiff it is.

Eek.. that doesn't look like it's going to pass 'dry fit' in thirty seconds.
