Thanks for the replies.
I took a look on the cylinder freeze plugs and didn’t see any model and serial number. Perhaps it was replaced long ago.
In the box of parts that came with it was a single screw transom clamp.
The tag on the clamp is 4287 which makes it a 38 Sportwin.
Did any other model in the 30s of similar size use that bronze lower unit?
Thanks for the offer pmT2 I’ll consider it.
