Finally got the 11-inch '54 back long enough to photograph properly!
And it really IS a good one, my prior stunt-Godzilla, also a Playmates '54 but of a totally different size that I got for $2.50, doesn't even compare.
And alongside the '95, it still looks great. As noted elsewhere, not a lot of articulation, the same as '95 with the neck, shoulders, hips, ankles, and tail base. One LESS in the tail, actually, '95 has a joint near the tip '54 does not, the tail is stuck lying flat.
Still, for under $25, a great figure, this has to be one of the 'best buys' in durability, size, and general value I've seen in a while. Also looks surprisingly close to the suit from most angles. It certainly has flaws, but my nephew borrowed it as soon as he saw it and it only just came back, so clearly as a stunt-double for expensive collectibles, while getting the interest of the next generation of fans, it works fine.
Thanks to clearance sales, this entire display cost me less than 35 bucks.
