MK2 Tropical ?

[Bavarian]

Hello
I ve bought not long time ago 5 British helmets and this one is very intresting
Because the screw was replaced by a bolt and some Tropical paint was visible inside
The liner is a JSC and W and in size 71/4
The helmet is made by BMB
It is havier than a Normal MK2
I think the Raw texure is the cause
Sadly it was overpainted Black and ot is too cold outside to remove the colour
What do you say to this one
Can this be true?
BR
