If you are referring to "investment" as will you get your money back or will it increase in value? - they aren't particularly rare.
If you men will you like it? - only you can tell that.
The model is a reasonably accurate representation of the M16 Multiple Gun Motor Carriage. These were used by Anti Aircraft Automatic Weapons Battalions (Self Propelled) and saw service in all theaters from late 1943-early 1944 onwards. The FoV model isn't bad. Sometimes the gun barrels are bent and need to be straightened..
