I have just dug my old collection out of the loft with a view to selling them all.
I just so happen to have quite a few mini rigs in boxes - no instructions, but in good condition.
Just waiting for the photos to upload.
In the meantime, the boxes ones i have are the following:
Endure Forest Ranger
Vehicle Maintenance Energiser (with all parts)
I do also have a desert sail skiff, but its not in a box and it missing a gun from the right mount as it broke.
