You're looking for the impossible. Geaflex started out as Folmer and Schwing in the 1890's. They serial numbered their products but kept no record of them.
https://graflex.org/articles/kingslake/ Kodak bought the company in 1905. They started keeping a record of the serial numbers between 1910 and 1915. In 1923 the date the entry was made into the record was added.
Around late 1946 or early 1947 the record becomes confusing then straightens out by 1950. In 1960 they started putting a date code
https://graflex.org/helpboard/viewtopic.php?t=3321 on each piece from which one can determine the month and year of manufacture.
Prior to the date code only the batch entry date was listed and cameras were built on demand. Crown and Speed Graphic 4x5 camera batches were 1,000 to 3,000 with as little as 2 weeks between batch entries.
Now a list of serial numbers dated by a member with access to the record and posted on this site was compiled and distributed to several other members. That list shows 879936 as a Speed in 1952 and 880105 as a Crown in 1953. Its likely your camera is in the same batch as 880105 and was probably made in January or February 1953.
Others have asked in the past but no record of Wollensak serial numbers have surfaced. Wollensak made Optar lens (Raptar rebadged).

Another member may post the date the batch was posted and its size but that is as close as you will get.
