[ATM] Sling study

[George Anderson]

Hi Tom

BVC is a "custom/secret" type of glass that was originally produced by 
Andre Taillon. He has since sold the business to another gentleman who 
seems to have a better grasp of quality control.
The most that Andre revealed was that his source of glass was from 
Pilkington who I believe are in the UK.
The mirror blanks are made from layers of BVC that are fused together.
Kind of tough to make a sling out of it though.
