For those into modern USN bird farms WU LA Model is now selling the AS 32A-35 Crash Crane, MD-3 tow mule and a fire tractor set in 1/700. I have not seen these since JAG and a Shapeways offering. Open cab on the tilly and not a square glob, finely done boom arms and a dangling hook. The utility tugs have wheels that are actually discernible from the chassis if you wear a magna-visor to see it. They offer other USN tugs which I am not familiar with.
Nice little investment in finer detail . Available at HobbyEasy.
