Tail light lenses

1958 Series 1 Station Wagon with tropical roof:

The lenses it has on but which is cracked has the following markings in the red outer lense.

DELLA - Red Beacon

In the Workshop Manual is a true drawing of the lense but it seems as if nobody know anything about these lenses.

Any assistance will be appreciated.

I would try emailing Dunsfold Land Rover a photo of what you're after as when I visited them last week, they had a selection of old glass lenses in a box going for very small coins. They're very knowledgable and helpful

I sent them a mail but cannot help, they informed me that DELLA was a original fitment by L/R.
I went on the internet but cannot find anything about this company.

Leyland/Albion has Della lenses but they are not the same.

So far a dead-end.

Thank you for the lead.

Regards,

Rudolph
