Can anyone help me verify and identify this lufwaffe belt buckle with tab

[Tomww2]

This is an unmarked with 1938 tab luftwaffe belt buckle i do not now what maker this belt buckle is from it appears to be partly denazified but this could also be heavy wear there is also a date inscribed on the back A 1. 10. 40. wich i think could possibly stand for attack on 1 oktober 1940 wich was the date for the last attack on Britain and also some other inscribing wich i cannot fully make out but it looks to me like wva

Thanks in advance

greetings Tom
