I really doubt that. Transformers are complex, expensive, specialised equipment, not something you just make a couple hundred of, nor does anyone have them sitting on shelves waiting for a customer to show up. Keep in mind, these weigh several hundred tons. While it isn't unthinkable that Germany may have dug up some disused ex-Soviet/DDR stuff in a warehouse somewhere (happened in Latvia and Lithuania after all), there is only a finite number of those.
I have internal konwledge how about the time required to make a transformer, and if there is spare capacity and the customer pushing hard then it takes to roll out one in six month time, if no worker in the plant touched the winding with dirty hands.
If happened anything like that it will fail on test, and add 1-3 month to the schedule.
Means untrained personel making transformer will take lot of time.
