If it means anything to ya...I know that the T-34 windscreens are individually made to each airframe.
My bro (F/A-18D WSO) flew here in a 34 a couple years back to get some X-coutry time (San Diego to central-ish Michigan). They took a hawk to the windscreen, while on short final....
You can see the damage to the windscreen and some remains on Mongo's(pilot) flightsuit.
Anyway...the moral of the story....they couldn't just send a mech. out with a replacement windscreen (because they are all different). Mech/contractor had to come out, measure, and custom make the part for this plane.
My bro and "Mongo" got a week + 1/2 paid vacation, while waiting on the fix.
