I’ve tried a few different mantles, and Coleman 11 are definitely the best. There are some listed on Amazon, but the reviews suggest that they may not be genuine! I want them for an Anchor 909
I use (in no particular order) Julian Shaws generic 500CP (ebay or his own website), Peerless #IIIs from justmantles.nz, Coleman 1111's from The Base Camp and I did manage to pick up some Optimus no4a mantles on ebay (I like these very much) . I have also used genuine Petromax mantles and the "Helox" version is a favourite. All of these work well. Coleman mantles were/are made in different countries and also over a long period of time. Many people will have opinions on which ones are best. Bear in mind what one person buys may have been made in Canada, another in the USA or the Phillipines etc..
@DarkDave , did you try from Amazon ? Or try this man in Canada : thenakedpicker sur eBay I bought him many mantles
