Hi all,
Further to what Cliff has mentioned, the Portee kit has been released under several banners, the kit has its origins in the Peerless / Max range and is excellent for its age, and has been released by several others notably :
Airfix - Portee with 6 pdr (comes up on Ebay regularly)
Italeri - Portee with 6 pdr & on its own (theres one on Ebay now in fact)
Revell - Portee with 6 pdr (still available in some shops but not in the present range)
The kit represents the soft cab Portee version and were predominantly used in North Africa, many were converted to GS versions for use in later campaigns.
Accurate Armour do a hard cab top conversion, and Airfix Mag did a conversion article many years ago on building the GS body, I have scanned this for somebody and can supply a copy if you want, (just PM me your e-mail address).
Its a great kit for its time (as were most of the Peerless kits)
Happy modelling
Ant
