Maybe this will help :

This is for the heavy "snakeskin" type.
Overall length from where barrel mates with
receiver to the muzzle=26.75 inches
Diameter at this point is 1.230 inches
Length from where barrel mates with receiver to beginning of first "step" in barrel= 1.172 inches. Diameter at this point is 1.140 inches
Length of first "step" in barrel= 0.365 inches. Diameter at end of step is 0.956
Here the barrel resumes a slight taper to a point 1.250 inches back from the muzzle. This is where the front sight mount is mounted to the barrel. The barrel for the L42 gets a military type sight base, and the Envoy/L39 gets a simple dovetail.
At this point barrel diameter is 0.791 inches.
At the muzzle of the barrel the diameter is 0.767
Using the below drawing (from shaw barrels) the dimensions are:
A= 26.75 inches
B= 1.230 inches
C= 1.172 inches
D= 0.365 inches
E= 0.956 inches
F= 0.767 inches
G= 0.791 inches
The barrels are 27.5" long.
Thank you! This is exactly what I needed
You should be able to find one of the barrels pretty easily these days as the thousands of No.4 based target rifles that used them have been almost all retired. They go very cheap in the UK, and could probably be found in Canada as well if you dig around among the old DCRA shooters.
