An etch of 32 mounting plates, designed for use with AC7/3 autocouplings.
The mounting plates simplify fitting the couplings to both ready-to-run and kit-built rolling stock. They also enable the couplings to be use on tighter curves.
The actual size of the fret is 82 x 102½mm; it is etched in 0.015″ brass. Each mounting plate is 22mm wide x 8mm deep.
