This is Armando’s drawing.

 

As I suggested the 10″ CRS refers to the distance between the centres of two holes

Hello

 

What does it mean B.M.S. FAB.?

It is a frame STAY.

Bright Mild Steel Fabrication. So it will be made from pieces of steel that are then silver soldered together.

From The Model Engineer’s Handbook root radius for the relevant gauges is given as:-

 

Gauge RR

63.5 0.9

89 1.3

127 1.8

184 2.5

 

all dimensions in mm of course.
