Do you mean an F4F Wildcat, or an F6F Hellcat? That you refer to a barrel-shaped fuselage makes me think you mean the F4F Wildcat, because it was sometimes referred to that way.
The old Monogram F6F Hellcat in 1/48 had retractable landing gear, or maybe more precisely, moving landing gear. Assembled according to the instructions, you could rotate the landing gear struts and push them back into the retracted position. The kit dates back to Monogram's first real models, and moveable features were something that the kids building models back then looked for.
Airfix made-still makes?-an F6F Hellcat in 1/24 scale, but I don't think the landing gear was moveable.
I know of no F4F Wildcat kit with moveable landing gear, in any scale.
Monogram's F3F kit had moveable landing gear, using gears connected to the propeller. You could rotate the prop and raise or lower the landing gear. However, to fit the gear in the fuselage, Monogram tooled the kit with the one gear sticking out a little bit on the left side of the forward fuselage. The F3F, by the way, was sometimes referred to as "the Flying Barrel", beause of its shape. It was the predecessor to the F4F.
I don't know if that helps you, but that's what I can think of.
Best regards,
