the only information one can get from the original bonnet/hood number is to clarify the production build date, the date of delivery, which is stamped on the dash locker lid plates if your jeep still has the original plates, there are no surviving military records of the history where the jeep served that could be ascertained from the hood number,..bare in mind so many jeeps were completly overhauled, rebuilt from overhauled parts, sometimes several times, whilst in service, so the bonnet may not be the original one
