I'm in need of a complete set of straps for the PN cord on my Model L- this is the cord that runs alongside the hose from the PN port on the canister to the port on the PN's sheath- the straps hold the cord to the hose. Does anyone know of a source for these without spending a lot of money? There's an eBay seller who has them, but his are white and kinda pricey. I'd love to have blue ones as original, and less expensive.
