Number of FAA-registered 337's

Let's look at another popular Cessna Model, the 310R/T310R.

Total production: 1332
Total registered: 500

500/1332 = 37.5% Active Airframes

The 310R is considered the penultimate 310, and even its 37.5% active is well below our P337H (51.6%), and not quite as high as our T337G (39%).

Let's look at some older 310 models:

C310K (1967) : 77/245 = 31.4% Active

C310F (1961): 41/155 = 26.5% Active

So the older 310s are significantly more active than our older models, yet our newer models are more active than the same-era 310s. Why do you suppose this is? What changed?
