Hello Mike!
I like your approach - something is still better than an empty space, when the real thing is crammed full, and the references are not so easy to come by, either. All models are inaccurate in some way, and it's up to the builder to say how accurate he wants to get. And still - a built model with it's inaccuracies is still better than a more accurate one that doesn't get built!
By the way - what colour do you plan for your M60? I'm not sure if you wrote about it before?
You've got quite a lot of goodies for the M48! I'm just wondering, that you start the old Tamiya instead of the new Dragon - I believe that would save you a lot of work.
Good luck with your builds and have a nice day
