Yes they did, but it was called the OVL. Also, Crouse-Hinds bought the rights to the Westinghouse fixture line up in both the USA and Canada, but Crouse-Hinds was later bought by Cooper, so later ones were sold by Cooper.
I may be misinterpreting your comment but what i mean is OV-50/OVLs marked as Crouse-Hinds and not Cooper. Up here in Canada we never had cooper marked fixtures, only Crouse-Hinds ones.
Also correct me if I’m wrong but i think the OVL may have just been a US name as the equivalent Cooper/Crouse-Hinds made OV-25s were called OVWs. No fixture by that name was made up here to my knowledge and they kept calling it an OV-25 until the end.
