It is actually 1:400 scale, not 1:350.
It is the Enterprise as she appeared as-launched, with the beehive island. Not as she appears now.
It is a kit which was originally sold by Aurora in 1965. Monogram got the molds when Aurora folded. Revell got access to the molds when they and Monogram merged.
Bert Kinzey, in his Detail & Scale book, called the [then] Aurora, a distant second best 1:400 scale model kit of the Enterprise. There were only two, the better was by Otaki (now sold under the ARII label).
Revell has not spent a lot of time, money, or effort to bring the kit up to modern standards. You are looking at a kit with mid-60s state of the art.
Revell re-released the kit in a box as big as the Tamiya Enterprise, costing almost as much as the Tamiya Enterprise, so it must be as good as the Tamiya Enterprise, right?
There are no dedicated aftermarket detail sets for the 1:400 kit. If you choose to go that route you will have to cobble together individual detail sets.
Squadron lists the same exact kit in their December sales circular at 53.96 USD. IMO that is closer to the true value of what is in the box, as long as you know its pedigree.
