AM has used the basic undercarriage in the kit but have detailed the main undercarriage parts by removing the moulded on break lines and replacing them with much more accurate detail, and also improved a few more small points of detail on the struts. These changes made it necessary to change the design of the main wheel doors, as the brake lines could not be integrally cast in brass to enable them to clear the support brackets on the kit parts. So AM removed the over scale support bars on the doors and replaced them with improved and more accurate scale details.
So now with this set you get a full set of brass undercarriage parts and two main gear wheel doors, cast in resin.
Please note current picture shows the masters in primer paint, the 5 undercarriage parts will be supplied in brass.
