I looked back at the link in the first post in this thread, and see that it was updated 8/20/07. The 1/72 CH-37 is there, but in text at the bottom is listed also a 1/48 H-21. I am mostly happy about the CH-37, but the H-21 is nice to see in 1/48. What a deal!
I recently reworked the CH-37 pictures on my website, rescanned and enlarged a bunch of them, and also added some from HMH-461 at New River sent to me by John Schroeder. Included are a couple of photos of CH-37's on escort carriers. Neat photos, I hadn't seen any of them on escort carriers before. Here's the link:
