DL44 ESB/ROTJ help

Months ago I purchased mauser conversion kit for DL 44. It was resin. Came with scope, muzzle, bracket, engine covers. It was much more affordable then the metal kits. But I FORGOT who I got it from. I cant find record of transaction.
Does anyone know who I can contact? (This is for conversion kit, NOT full resin kits you see on e-Bay)

Thanks
