RG570EX Japan: NRG550LD on neck and *BG570 on pocket. Need your help to ID this! Pics

[Tubarão Guitars]

A friend of mine have just bought that RG570EX here in São Paulo.
Anyway we are confused by 'numerous numbers', as you can see here:

Can't do much to help, but that's a cool looking guitar

What exactly are you asking? The 570 and 550 share the same neck on many models, this is all it is.

I dont think thats a RG570EX.

My RG570EX is matt silver with mirror sharkfins and pearl neck binding (no headstock binding)

They did the RG570EX in RBF (Royal Blue Flat) and CPK (Cyber Pink) also.

Tubarão's guitar is a 570EX-GK (Galaxy black). I think this finish was for the Euro/UK market. There are not many of them around, as far as I know.

i agree with thedonutman, it is probably not RG 570 EX.

what i have in mind :
1. RG 570 EX is true had cyber pink and royal blue flat finish, but it has newer sharktooh inlay material, something like sharktooth material in RG 2570 E, what do they call it? brown / mirror sharktooth or something?
2. the inlay material in that guitar in question is old sharktooth material.
3. RG 570 EX does not have headstock binding.
4. could it be an RG 570 with after market modification with RG 550LTD neck on it?

I saw one thing exactly like this on ebei, it was called RG 570 DX.
I never saw anything with designation RG 570 DX before, but after i saw one on ebei, i have to believe that RG 570DX does exist.

You know, psychoshredder, that does look like an RG550LTD neck. Here's mine (sorry it's not a great picture):
