my guess is its just cuz spider's have eight legs, and with the waldoes (thats what theyre called), he only has seven.

I'll be Starked... you're right. I just looked at my CW issues and he does have only 3. Why are my memories of him having 4? Is it because 4 is a more satisfying and aesthetically pleasing number? Is it because the most recent Spider Armor I've seen was in Avengers: Initiative (the Scarlet Spiders), and thus my memories of CW Spidey just naturally assumed he had 4 as well? It's odd. 3 does seem off when I really look at those CW pictures... like he should be off balance.

For u guys info
Civil War - Iron Spider (Peter Parker) >>> 3 arms
Scarlet Spiders ( Red Team) >>>> 4 arms
Tony got the data from Peter's 'Iron Spider' Stark armor, then he produced another 3 advanced version of the iron spidey - Scarlet Spiders.
Post-Civil War, the Scarlet Spiders are a group of three unknown people of the Initiative who identify themselves as "Red Team" on the field, first appearing in Avengers: The Initiative #3. All three of them wear an advanced version of the 'Iron Spider' Stark armor which Spider-Man formerly wears pre-Civil War and during the event. During their first appearance, they take down the Shocker, Boomerang, and Hydro-Man. War Machine identifies them as "Scarlet Spiders" when contacting them. He also implies that they will be the successors to the Spider-Man identity once Peter Parker's powers are removed permanently. In Avengers: The Initiative #5, the three Scarlet Spiders are revealed to be part of another group called the Shadow Initiative under the command of Henry Gyrich.

Sweet
and the Civil War issues I've got - hes got 3 arms - which I assumed was a misprint/misdraw
he should technically have four waldo arms

To save on plastic I guess

No worries, guys... it's just every single instance of the Iron Spidey armor I've seen in the comics had 4 arms. All through Civil War he had 4 arms. Odd.

Sirs, the Iron Spidey was a repaint of this fig made by Hasbro...
Customer said the factory red and yellow were too candy/toyish so goes the repaint.

he only has 4 in some comics

Looks freaking sweet comic accurate! But wait... shouldn't he have 4 mech arms?
