I just got this in the mail and after carefully examining I’d say that this are welcome addition to the aftermarket goodies for the 1/48 Legacy Hornet. This are from Flying Leatherneck Decals by Dave Roof.
The pylons are 3D printed and details, including the rivets and sway braces are beautifully done. Once painted and pin wash treated details will surely pop out.
This one was taken with the 1/48 Hasegawa legacy pylons. The hasegawa are the light colored ones. You can see the difference in the details with the 3D printed ones.
