I submitted a picture above of the way the Ericson 41 nose is supposed to look in profile. Just visualize the tip filled in with a solid teak triangle.
Keep in mind that if you restore the teak triangle look up front, the current headstay tang will not fit. You would have to have someone unbolt it, straighten it, and then reinstall it. Doing so might interfere with the furler. As I speculated above, I suspect the furler is why the change was made in the first place. The pulpit on your boat is not original (nor are the stanchions nor stern rail). It is more narrow than the original, worsening an already fine (albeit beautiful) bow point.
In the short run, if your goal is to return it to sailing ASAP, I would have a marine carpenter custom fit a piece of teak to replace the block that is currently there (that does not appear to have been cut to the proper angle). Then bolt it through the deck.
In the long run, if you want a reliable anchoring system, you are going to have to figure out a way to install a bow roller up there. IMO replacing the teak triangle is not the way to go unless you made it about 30 inches long, which would look ridiculous. If you want to do a complete restoration of your boat, your teak toe rails are going to need to come off anyway. Based on the pictures most of the bungs are gone. I'd be shocked if they didn't have significant dry rot (they did on my boat). You may want to try to configure a system that integrates a stainless steel fabricated nose section (like a Hinckley 35 Pilot) that transitions seamlessly into new teak toe rails.
Restoring your boat is going to take a ton of work and money. I'm not trying to be discouraging. I speak from experience (a 1968 Ericson 30). But if you stay with it you will have restored one of the most beautiful boats ever designed.
