Coughtrie BB15 bulkhead for GLS lamps

A very nice type of fitting I have been on the hunt for for a number of years - a few days ago, I found this reasonably-priced example on Ebay and was finally able to add one to my collection. Whilst this is a remarkably clean example, there is a tiny bit of damage to one of the corners, but this can hopefully be solved through an eventual full restoration. I've always loved the slightly purplish glass these have.
