Closest RL Match for Fictional Helicopter Design? Erm, not sure if this is the best place to post this but it seems like the best place to get a pretty straight answer thus far in my search.



So yeah, this helicopter is obviously from a cartoon – but I'm writing a story and I wanted to refer to it more specifically if possible, and also I'm just plain curious about what real rotorcraft(s) it was most likely based off of. And so far the entire rest of Google has not been much help. Plus, I've tried comparing some of the era models (i.e. 1960s, 1966-1968) I've found pics of on my own – but yeah, I am pretty clueless here. =(

Can anyone help? Thank you so very much for your time!

EDIT: I mentioned the year and I put the source in the pic description, but I'll reiterate both here. It's Michi/Trixie's helicopter from the Japanese anime Mach GoGoGo/Speed Racer 1966-1968.
Possibly the Bell 47J:

The Bell 47 was configurable with floats more in-line with the image originally posted, but I can't find a lot of images with the full skin frame and floats, but here is one:
