Hi again Chas73170,
It'll be a bit of a challenge finding this brand online, the brand owners have strict reseller policies about not doing business with anyone whose sole enterprise is e-commerce and does not have a legitimate store front.
The Calcutta line of products are available only through authorized dealers/retailers. If you're interested in become a dealer yourself, I suggest visiting this link:

They require at least $2500 worth of products for your first order to qualify as a dealer.
Hope this helps.
