In '81 they were using Atkins Hoyle some 38's I have seen. If not that brand, perhaps a Bomar?
Admittedly I do not know when they consolidated on Lewmar...
My 1980 E38 has Atkins & Hoyle hatches in the salon and v-berth. The ones they sell today are nearly identical looking to mine. They sell replacement arms and stuff. You may have to call them - they'e up in Toronto, Canada.
