On Sunday January 12 2020, Szirmai Gabor from Hungary left the following message for Walter Wirtl:
"I have a document for WIRTL WALTER name from The hungarian technical university before II WW. That is not yours? (the Wirtl Walter family during the second world war lived in Budapest, and made for machine failing powder. When Budapest was caputt (by the russian solders, the family flucht to German. But left few peace of his document and few piece of furniture on those road, which the first russian tanks rolled to BUDA district. The university controll-book (examine-book) remaind under the ruinen in TOROCKO-street, and now is in my desk. Szirmai Gábor"
