Another buy from my trip to the Midlands Model Engineering Exhibition.

A small cast iron angle plate.
Nominal: 3" x 2.5" x 2"
Measured: 75.4mm x 63.5mm x 50.5mm
The slots are 8mm wide.
I just checked the accuracy of the angle with a square and there is no daylight.
Price: approx £8 for this size.
Good price and is as described, you cannot go wrong with this.
