Aspera engine wanted

Hi Looking for an Aspera engine for a generator, & a villers orJ ap for a winget Concrete Mixer, both items rescued from a skip today without the Bloody Engines! Also does anyone know where I can get an exhaust for a Briggs & Stratton Ride on Mower? Pulled three from Same skip minus the Bloody exhausts! Suffolk Area preferred.
