747 Classic/ A300B4

[looth]

I understand it’s early days, but I’m curious to know what the variants you guys are planning to work on the 747 Classic and the airbus A300B4

Is the A300B4 the -200 or the -600 variant? Personally I like the -200 since it has the engineers panel

As for the 747 Classic, since the cockpits are so similar for the -100/-200/SP, I can hope for variants yes?
Perhaps even the very rare -300?

What about engine variants for the 747?
