"I think it may even be a Guns-A-Go-Go ACH-47A kit as well"
I should hope so...... I could be wrong but I'm pertty darn sure the GO GO Hooks were the only 'Heavy' armed Hooks in Nam? ......and I think we are in luck cuz its Italeri who did the 1/72 scale Guns a Go Go version.
Speaking of 1/48 Helos.....Last weekend a large local model club had a big 'Model Show' ( not a contest ) at the the Museum of Flight here south of Seattle and there was a built 1/48 MRC CH46-E .....and I was kinds surprised how small that kit really is......NICE!.....but small......The Chinook is a bit larger and fatter than a Seaknight right???
If you ever visit this neck of the woods....you gotta visit the Museum! it is amazing and the new Wings of courage wing is two floors with the first all WWII aircraft including a F109E and of course a P-51D, P-40 War hawk and many more and the second floor is all WWI Aircraft....both floors have interactive displays....sit down flight simulators, scheduled shows and movies.
Straighten up and fly right.....
