Hi

I would like to build a scale 20 Ton tube wagon from original drawings, but found on the drawings something I don’t know by the measurements N.S.B.C,what does this mean.

To the OP – I think you've read the drawing wrong.

Try NBSC: New British Standard Channel, followed by the section number.

The drawing I think you're referring to says NBSC13 – 10" x 3 1/2", as shown in the Dorman Long handbook page 41 here: **LINK**

On page 60 you can find details such as the taper angle of the flanges and the section thicknesses.

If it had been an 'I' beam, it would have a NBSB reference, equal angles NBSEA, and so on.
