260 cobra flame thrower ignition

[4-2v cyclone]

Ive seen old pics of early compition cobras with flame thrower ignitions, were these original from Shelby like this? I have an NOS one, but mine has a chrome cast plate on top, and the pics ive seen they appear to be painted, does anyone know what its worth? I was thinking about selling it, theyre pretty rare, but dont know if they bring any money.
thanks

Some very early SAI racing with HP260 engines did include this type ignition system. I have seen a new old stock 1963 vintage set up complete in the box with paperwork offered for sale several times but the seller doesn't seem to get much interest in his offering.
