Look for a business that does welding and makes iron railings.

You can get rid of the sharp edges and rust yourself, with a file for the edges and some steel wool and then rust-inhibiting paint for the rust.

Removing the gas pipe - a hacksaw and then some filing of the rough edges

Dunno about the hinge repair. Can you post a picture?

Don't know where you are located, but there is a place in northern VA that refinishes old pieces such as the old iron garden furniture. There might be a similar business near you. Good luck. Sounds like a neat piece to have!

Thank you cyn and lazygardens. I'll try both of those ideas. DH has suggested an auto body or an antique car restorer but I suspect those types of businesses wouldn't want to take on something this small. Thanks, again.

Take it to a sandblaster. There is usually one in every town around here. That will clean it up and then you can see what needs to be removed. Someone at the sandlblast shop can probably refer you to a welder in town who can remove the parts you don't want and clean up all the sharp edges.

Thanks, pris. That's a good idea, too,
