I have MR Models' M88A1 interior. Now I can put it in an A1, of course, but I'd like to use it for my straight M88. I've been told the airfilters in the back of the fighting compartment (is this the right term for an MRV?) are vertical rather than horizontal in the M88, and have one or two fuzzy drawings, but I'd really like more information. Can someone help me out here?
Thanks

Olaf
