If you look at the evolution curve of Revell kits, you will notices that there are some serious differences in style and technique.
They went from some seriously detailed, yet very finicky and poor fitting, mainly due to having everything open up.
To some very simplistic kits that shared lots parts with other kits
And then to some quite decent kits
They started a detail comeback, but, some of the subjects where quite lackluster and rather unappealing
And now some nice stuff, but, with questionable specs on some of them
Unlike AMT or MPC, who kept a pretty linear style of design and kit execution, Revell has tried quite a few styles of kit production and no doubt some of them had to do with finances.
Revell appears to have taken more risks on how their kits have been produced and some have been hits and some horrible misses.
Myself, I am just glad they are still around and making kits. The very first kit I built as a child was a Revell kit, and overall, most of what I have built has been Revell. I have a soft spot for them
and their kits. And, they started in California, and that means something to me!
