Historical Note on Titanic Prime whose Digits are all Odd

According to David Wells in his Curious and Interesting Numbers, 2nd ed. of $1997$, this titanic prime was discovered by Harvey Dubner in $1988$, but this has not been corroborated.

He also reports that it is the largest known prime whose digits are odd.

This was likely the case in $1997$, but research is needed to see if this record has since been superseded.
