The ship name does not match the company.
Both companies had Victory ships for a short time.
I cannot find the item on e bay so cannot say which ship it is.
Brocklebank Co ships had a black funnel with a white over blue band.
The name Stanhope belongs to a Stanhope S.S.Co vessel owned by J.Billmeir.
Brocklebank ships had names of Indian provinces and towns.
The way to work out which ship it is is down to the funnel colour.
