That is unfortunate, i like having the hardcopy manuals and wish I could find some to buy.There are available Charles but hard to find. The chassis and body come in two parts and the engine comes in a single manual.
I had a few sets for sale on this forum but someone got up me excusing me of making this forum like eBay so I pulled the sale.
Sorry but no longer for sale.
I can take some pics and add part numbers if you like.
