My sources show that the Aurora CH-54 was released in '69, and featured separate doors which could be mounted open or closed. Judging by that kit comparison linked to by 'Tailspinturtle,' it would be worth ordering. I didn't know this stuff was still available overseas. I have the Revell kit, and while I never did build it, it looks to be pretty decent. Wouldn't it be cool if Monogram up-scaled this kit to either 1:48 or 1:32??
Here are a few scans from the driver's manual... I promised these to someone here a while back but I lost the e-mail contact information.

(edited to add that for some reason the pictures do not enlarge when clicked on... they are actually about 8x10. I don't know if I did something wrong or what)
