Chris,
This is the best I can do for aft bulkhead attchment points:
Pic 1
Dad thought the two rings you can see on either edge of the bench seats were the most likely points for the monkey belt to clip into. However, he wasn’t 100% sure. Mel or Grandad, what’s the small rectanglular attachment point directly behid the center of the bench seat for? You can also see the four ammo boxes this bird has.

This pic shows one of the seat belt attachment points. Sorry, I forgot to move my hat and notebook for this shot!

Here are the attachment points on the floor.

The jump seat in place in the cabin.

This last one shows the seat belt attached. You can also see part of the jump set to the left. I dug out my notebook and the jump seat measurements are as follows:
Main legs: 12in. high, ~.78 in. diameter
crossbraces: 16 in. long, ~.5 in. diameter
Seat dimensions: 15.75 in. deep x 18.75 in. wide
Seat back height: 24 3/8 inches
Well, that’s about all I got I’m afraid. I have numbered the pics so anyone can comment on specific ones. I hope that helps.

Best I can tell from the photo is I think that rectangle bracket is an attacthment point for the bench seat.
Please note Veitnam a/c were the only ones that had the soundproofing and doors open or removed. In Korea it was to darn cold to leave to have them open in the winter
Grandad,
I hear ya about the doors. The bird above is clearly not designed for guns as you can see that the door HAD to be open for the ammo chutes to go though, In fact, this is one of the two TOW birds that flew in VN. Do you have any pics of your ships from Korea? If so, I know I’d love to see 'em.

Those pictures are on slides and negatives and are packed away right now. I’m moving on Sunday and will need to stay with my son till my new apartment is ready, so it will be awhile
Hey guys,
I would have never guessed when I started this post there would be so much interest.Thanks so much and keep the info coming!I should be able to post some pics of my cabin progress soon and you guys can critique the accuracy of what I have done.Waiting to borrow my moms high dollar digital camera to take some good shots.Thanks again for all the info,and again If you have them,Marko I would love to see any diagrams you have of the area in question.Chris
Hello Guys!
Uf, they are really keeping me busy at work lately, so I haven’t been able to post as many replies as I wanted. Well anyway, here are the attachment points diagrams from 1968 UH-1C operator’s manual:
Now, this diagram is not drawn in scale, so You have to use the F.S. values (in inches) to calculate the exact position of the attachment points. You will notice there are three attachment points in gunners positions:
To make determining the exact location of attachment points easier, I also include a diagram showing the installation of internal rescue hoist; here You can find F.S. values for aft bulkhead and door post-using this values You will be able to locate all attachment points accurately 
Mel, I believe legs on jump seats could be adjusted to some extent and still be completely vertical (perpendicular) to the floor. I think the following image is the proof of that; note how the left leg is the inner most position and the right leg is in the outer most position. I believe sliding legs inward or outward made fitting the jump seat to different attachment points possible-all within given limits of course
Ray, great interior shots by the way!!!
Marko
I can see the only way we will “resolve” the jump seat attachment points is for me to go out and find those Mike models and see how my jump seat fits in the gunners position. And take pictures to post of course!
Mel,
I believe you put the seats in the way you say, I just also figure my dad did it the way he said as well. I would LOVE to see pics of the seat in place. I have plans to do that myself at the earliest possible convenience. I look forward to whatever you find!

Hi Mel,
I’ve read your interesting discussions about the Hueys, in particular about the UH-1C, that I’m going to build in 1:72 scale (Italeri) and that I want to insert into a Vietnam diorama. To this purpose I would like to konw if the Gunship Heli UH-1C of the US Navy HA(L)-3 (Bin Thuy, 1970) was equipped with an M60 machine gun hanging from the ceiling. Can you help me?
Regards
Vincenzo
Vincenzo,
I’m not an authority on the Navy Hal 3 birds. Also not at home to look through any refferences to try and help you out. Maybe some of the other guys out there can help you. Good luck with your build!
