If you mean the cannon ball shaped road torches, they are most easily found by a Google search for "smudge pot" torches to find a retailer near you, they are sold by several companies as patio torches and are made in China, prices vary greatly from seller to seller. Vintage originals can be found on eBay. And last time I checked (last year) Fisher-Barton of South Carolina still sells the original Toledo Torch and replacement parts but are expensive, about $25.00 ea.. Rockford tool Co. sells a two pack of stainless steel torches at about $60.00/pr. through Amazon.com. so your least expensive option is most likely the cheaper painted finish Chinese knock offs.
