Parker 51 With "Bubbly" Texture on Hood

[RayCornett]

I have a Parker 51 desk pen that I obtained a number of years. It arrived with some sort of bumpy texture on the hood. It also seems to be on the inside of the hood but not to the same extent as the exterior. This is the best picture I could get for now. It COULD be some sort of clear spray on coating that dried too fast to smooth out but not sure how to find out. This is on a 51 desk pen with chalk marks still intact on the barrel.

Any ideas what this is?
