Rainham garage scrap metals RM13 7AA

These were left behind by my tenant. The parts include an axle, BMW engine, drive shaft, seats, pedal and motorbike wheels etc. There are also two 4.5m-long (welded from two parts each in the middle) steel scaffold pipes. Piaggio scooter has the keys, although I'm not 100% sure they work. I've got no paperwork/logbooks. Looking for collector paying the best price and able to collect tomorrow.
