This is a Blender/Food Processor that have the same base. Purchased in 2011. The only numbers on a sticker on bottom of base says "Type 243" and another is under a barcode F2437051M/861-30011. The blender is very easy to afix to the base but the food processor is very difficult. I hope to find the "trick" to attaching the processor to the base. Any help woulde be greatly appreciated.
