Unknow 40W 4300k tube

Today I've found in a recycle bin this tube (together the two Osram 40W/30).
It's slightly used and appear to be a standard CW color.
Any guess of the manufacturer and how old it is?

I’ve seen the very same tubes installed on numerous places and in first place they look Philips made but they are not! I suggest that they are from eastern Europe. Romania? Bulgaria?

Thanks for the information.
Yes in the first place I thought too that it was Philips made, but there are some differences. For example the end cap seems plated with a sort of gold looking material and not brass like old Philips tubes.
Electrofar seems plausible and they are from Romania:
