Chris,
The damage is only on the new TE2 helmets.
My Brian R and ESB replicas have old TE1 bumpy caps made years ago, so there was no damage on those.
The TE2 kit i have (the Dave M replica) had some damage to the front above the brow trim and at the back on the left as you said. I just used a small amount of car body filler on the outside to fill the damage.
Thanks,
Keith.
