Agreed with Gunny here,
You need 3rd Pattern Vibram soled junglies, if you're going down the screen accurate route. And NOT the Panama soled ones.
If you look here, you'll be able to see the differences.

It's likely you'll be trying to score some old issue stock with these and the Vibram soles are a bit hard to come by, so expect to pay good money for them unless you get lucky.
Most (if not all) of the Repro boots, and more common surplus stock are of the Panama soled ones.
Now, if you don't mind the sole not being correct and as Gunny notes, you're standing on it for most of the time so may or not may be an issue.
(I suspect from our conversations, the fact that you know it's there will cause you an issue! I understand.)
You can go for repro boots or modern issue ones, but buyer beware you do get what you pay for.
I've seen some repro boots that are actually pretty decent, and some that are really nasty.
I've plumped for some modern Austrian Issue jungle boots (I'm not too much of a stitch counter, but I can empathise with those who are). They are a sort of hybrid between the 2nd pattern and 3rd pattern boots. They have a leather back-strap up the rear and a sole that is closer to the Vibram (whilst not identical). The main differences are they have a small detail on the heel and toe of the sole that is not present on US jungle boots and the sides are nylon and not canvas, although the canvas reinforcement is present.
For me, whilst not totally screen accurate, they are good enough and of an acceptable standard to look the part.
They were reasonably priced and are as comfy as hell. I've worn mine pretty much every day for since I bought them, about 4 months ago.
I'd buy them again in a heartbeat.
