Unfortunitley Jeff Ward's name is always thrown up on Ebay to try and push up the prices
, the real deal Mini Elsinore is a C&J frame with a sleevd down CR125M motor, there were many variations after Jeff Ward Racing Products brought out the first Mini Elsie, DG, FMF,CH, Miller Mano and probably a few other aftermarket companies had their own kits for sleeving the 125 down to 100cc but C&J at that time were the only frame company to make the frames for these little trick bikes.
Those pipes do look familar Geoff
and yes your pipes will fit the Mini Elsinore with a C&J frame
