Marklin HO 3628/3828 BR E 91 HAMO with 5 pole motor, new MFX decoder new in box.  Model was one Marklin made with SERVICE MODELL written on both sides.  They sent these to dealers to give to customers while their Locomotive was being fixed so they would not be without a locomotive. Rare to see these.  They gave them the model number =3828 but are exact replica of the 3628.
