Hi Mike ;
Excellent work on your UH-1N and also the AH-1W and that awesome kit bash CH-53E .
I thought about doing something similar in combining a CH-53D and a MH-53E to build a CH-53E but I chickened out because I though it would be too difficult .
However Sir , I think your effort is just amazing .
If your looking for some modern USMC markings in 1/72 scale , which I mostly build in then you are in luck .
Another FSM modeller recently put me onto this site...

The have some awsome 1/72 decals and I picked up quite a few sheets of different U.S military aircraft and helicopters ranging from the Vietnam War to the current day including a nice sheet 72-035Cripes A Mighty Marines .
There's markings for a current UH-1N ,CH-46E , F/A-18D also a winter camouflage AV-8A Harrier ( I had to get that one ) .
Anyway the 1/72 Wolf Pack range of decals are quite extensive , over 7 pages of different sheets , I ended up buying 5 sheets and with 5 to 6 different aircraft on each sheet including a full operational history of each aircraft you wish to model , this is by far the most comprehensive decal sets I have ever seen !!!
There is also another source for Wolf Pack decals in the U.K , called Fantasy Printshop .
I picked up a couple more sheets from them as Mill Creek Consultants had sold out of some 1/72 sets I wanted .
Sorry for the long post but again I think your scratch building workmanship is "Top Notch"
Well done
John
