Thanks for the continued help guys. I've been back through the weapons and googl'd all the suggestions and its helped me to ID at least half of the weapons.
The canopies don't seem to match any of the manta force vehicles i could find... any other suggestions? Similarly the action figure doesn't appear in any of the M.A.S.K or GI Joe lines - he is stamped 1985 MB Hong Kong... anyone know who he is?
Stargeezer - Thanks for the link to the WHOBIT site... what a resource! I'll start checking out some of the machine guns against the database over the next few days.
ODB - Sorry to hear about your broken hand, hope it heals soon. When you feel up to it, if you could help by naming a couple of these bits and pieces that would be really appreciated. Hopefully now that half of them have been marked off it makes it a bit easier too.
Thanks again!
