Hi Steve. Your Eco
is not only a kissin' cousin to the Boler
, it's also a kissin' cousin to Scamp
and a lot of the other egg-shaped trailers.
For your hinge repair, I suggest you order the stainless steel parts from Ian Giles. Ian is a member of this forum too. You'll find what you need about halfway down this page: Camping Treasures - Camping and Glamping Accessories | Vintage Trailer Parts & Hardware
Do you need just the outside handle for the door or inside too? If you just need the outside, you can get what you need at a Big Box hardware store. It's just a garage door handle. You'll need to cut the square shaft to the proper length. Use your old handle as the guide.
IF you need both parts, you can order what you need from Scamp
