Seeking date of manufacture for a Flottorp prop

[roland.t.reimer]

I have a Flottorp 72A48 - S/N A24380E
I would like determine the date of manufacture for the prop.
I don't think its that old, but I'm curious.
It is a very cool looking propeller, with many, thin laminations.
Anyone have any ideas?

Unfortunately to my knowledge this information has been lost in time. Only Sensenich has information available on serial numbers and manufacturing dates.

Thanks Lamar

I've heard that the Flottorp factory burned down - any idea when this happened - ie; when they stopped producing propellers?
Or any info on Flottorp for that matter?

I don't know if the factory burned down, but I spoke with Ole Flottorp's grandson years ago, and he told me that a fire in a storage facility destroyed all or most of the records from the manufacturing, which is probably one other reason that dates of manufacture based on serial numbers are unknown.
