The kit is definently an old ERTL mould as the brand is still on the sprues
The scale is 1/48.
Lots of decals is available commercially, but there are 6 options included in the kit, so there should not really be any need for extra decals. There are decal options for Brazilian, Dutch, British, New Zealand, US planes. I cannot remember the last decal option.
There are also the option for bombs or a drop tank in the kit and two different cockpit styles.
So far an okay kit, but nothing out of the ordinary. Looks like a good kit for a reasonable price although I have not finished the kit yet.
