Raymarine/Autohelm ST front cover needed
I have an old Raymarine/Autohelm ST30 knotmeter with a damaged case. The damage is to the screw posts in the 4 corners of the front cover of the instrument. The screws for opening the case pass through the back into these posts in the front cover. Three of the posts are cracked, so I can't tighten the screws to seal the unit.
Does anybody know where I might get a replacement front cover? I tried Raytheon, but they don't seem to have any parts for this old of a unit. Googling didn't get me anywhere either.
The display still works fine, and I'd like to retain the ability to open the case. So I'd prefer to get a new fron cover, instead of just gluing the case closed.
