L1B, Old passport with prev visa damaged

[dhilip]

I am appearing for an L1B visa interview with my current valid passport.

I had an L1B with same employer, on my old passport.
Both the visa and passport expired.

The old passport was damaged in a flood so much that the first and last pages are not readable at all.
Visa page is in good condition.

I cannot get a replacement for the old passport as it is expired and cancelled.
Do I need to show the old passport during visa interview ?

Thanks.
