Tri-ang (Minic Motorway), (+ Model railway?), classic Slot-Car or Train Set, P5 Power Controller Transformer unit,

200-250V AC input with reversible controlled and uncontrolled 12V DC outputs,

Tested and in good working order.

Now over 50 years old! and long since discontinued, hard to find.

Size: 3 3/4" (8.5 cm) wide x 5 1/2" (14 cm) deep x 2 1/2" (6.5 cm) tall

Multiple uses, however, I remember using one of these to control my 1960's Triang, Minic Motorway car set.

Interesting collectible for the classic toy collector.
