Thorn-Mazda 100W Externally Sprayed Red Lamp

Here is a Thorn-Mazda 200-250V 100W externally sprayed red lamp. I cannot see a date code anywhere, does anyone know roughly when this might have been made and also the factory..? Thanks to Andy (LG) for three of these :-)

Unfortunately the spray coating would have obscured the date code, so the best we can hope for is an approximate age based on the packaging, help with this would be appreciated. Wonder

No idea about the production date. Is this an original lamp or was it painted by a third party?

It looks to be original, the card that supports the cap does say Red on it.
