I shudder to think what your house looks like with big-box-bought plastic shutters!

The plastic ones don't do your older home justice and they are too short for your vintage windows...wooden replacement ones are available at a reasonable price. I replaced mine with these. Used one coat of primer and two coats of paint...they still look new after 7 years.
