The other NATO nations (excluding Germany) are likely to have followed a similar production pattern to the USA.
The PACT though, given they run on a command economy, and they'd been at war a bit longer, were probably well on their way towards a high production level, however their forces were nowhere near as fresh as those in the West by the time Germany and Poland butted heads.

And then there's the "lesser" conflicts - Pakistan/India, Australia/Indonesia, and so on. Production patterns for those combatants would look very different again due to a number of factors, perhaps the main ones being the funds available to pay for those wars, history of the conflict (the P/I one going back a long time), and the intensity of operations.
