Winchester 32-40-165

[LeadHead72]

Here's another that came in the mail today; a 32-40-165 made by Winchester. The blocks mate up super tight and it's in nice shape overall. From what I've seen online most of these seem to be simply marked 32-165, not 32-40-165 like this one. Can anyone offer any information since I know nothing about these Winchester moulds?
