The set can be used on either the Dragon 7.5cm PaK 97/38 w/Heer Gun Crew (kit #6445) or the Italeri PaK 97/38 AT Gun with Servants (kit #6460) as the modifications are the same on both kits to add the metal barrel.
As with all RB Model sets there are no instructions or fancy packaging, just the parts in a zip lock plastic bag and a simple B&W label which does mean on a barrel of this nature using some analytical skills to work out how to fit the barrel parts together, but if you have experience with metal barrels and multi-part muzzle brakes it shouldn't be too much of a problem?
The set has the aluminium barrel tube and four part brass perforated muzzle brake and collars plus two etched brass parts. The only cleanup of the brass muzzle brake is some burs on the inside that can be easily removed by running an old #11 blade around the inside. The etched parts are a quite basic and as they are a little thicker there is a seam around the parts that will need to be carefully filed away for a clean edge to the parts.
The barrel tube is hollowed out slightly without any rifling which isn't really noticeable once the muzzle brake is attached so is not a problem with the fit of the brass collars a little sloppy and you will need to take care to align these centrally during assembly.
There is two brass collars, one smaller and the other larger which also has the distinctive bracket attached and there is an indentation on the bracket that makes lining up the collar very easy while you solder (or super glued if this is your preference) the parts together. Soldering does provide a stronger bond and is the preferred method of assembly to avoid the parts coming apart while handling the assemblies.
The muzzle brake has an end cap with an additional etched ring added and again soldering these together will result in a stronger bond as well as allowing you to eliminate the join seam between the muzzle brake and cap very easily.

Fitting the metal barrel to either the Dragon or Italeri Pak 97/38 kits is the same for both kits where you firstly glue the two halves of the gun/barrel together and let the glue dry completely, this makes cutting the barrel off much easier than if cutting the parts individually. After cutting away the plastic barrel there is a hole exposed which again is the same size on both kits with the long locating neck pin on the metal barrel designed to fit into this hole.
Inserting barrel neck pin into resulting hole after cutting off the barrel
is the same for both kits.

and the plastic kit muzzle brakes showing the improvement in detail definition
This set will add considerable detail to the kit barrels with the perforated muzzle brake being most impressive.
Highly recommended
