Junkyards, maybe Ford. Seems like that's the style clamp that came stock on my 77 Ford 3/4 ton 4x4 with Cleveland 400-M.
There's two types of clamp in that picture. The one that's black and you can barely see is the type he's calling a swedish clamp and he painted it black. See here: http://classicroad.com/modelA/engine.htm The other type- the ones I think you're probably looking at are called 'wire hose clamps'. In addition to the other suppliers already mentioned, a quick google search turned up this for a supplier online: https://www.deerelydeparted.com/p-401-wire-hose-clamp.aspx Those tractor guys have a special kind of sickness . From the description: "Our two wire John Deere hose clamps are made from steel so they are guaranteed to age like the original.." That doesn't sound like anyone here does it?
In my opinion the "swedish clamp" looks like a standard clamp with heat shrink tubing slid over it and shrunk. Eric
Everything Rolf does is Swedish...but that's ok he has that affliction. Some of us are Norwegian, as a result, life is simpler for us.
Because I am Scandinavian I was going to joke that this is the "cheap" way to make a "Swedish" clamp but you beat me to it! I had an electrician give me bags and bags of heavy duty adhesive heat shrink in diameters from .25" to 1.25". I've used it on exposed fastener shanks, tool handles, homemade sheet metal brackets (like to hold fuel filters), over sections of brake line or fuel line to protect it, or for anti rattle. It works great and gives stuff an OEM look. Never thought of using it on hose clamps... Eric
