... plus complete repaint (from iridescent lime-green-purple to sand-green-brown with desert sand weathering,) addition of reins/bridle, huge saddlehorns, tonnister saddle bags etc (which visually changed the proportions versus the no-saddle look, with riders sitting higher).
And even within the UK pics, there are angles where even the earliest Dewback looks kinda cool and more like a real animal if imagined without the frill:
The point I'm making is that I'd rather see a collectible that takes in the overall look of the original Fred Pearl design but tweaks it to believability - so stuff like thick elephant-like feet/legs (not skinny bird legs like in the redesign,) long thinner dinosaur-style tail (rather than short/fat stumpy tail in the redesign) and including details like the ribs showing on the torso that are visible even in the iconic promo pic.
And there are a ton of ref pics for the screen-used saddle/horns/reins - at least make those accurate to 1977 rather than the significant redo seen on pretty much all modern-era collectibles.
