Unbranded 11" Aluminum Shallow Colander Steamer Insert
A vintage solid aluminum combination steamer insert and three legged colander strainer. Unbranded maker - most likely this was part with a pot set. Well made sturdy object.
The last photo shows how it will fit in a Revere Ware 9" ID diameter pot - it will fit a larger diameter pot as well 9-1/2" to 10-1/4". Your lid would need to be aprx. 10-1/4" to 10-1/2".
overall size 11-1/8" diameter x 3-3/4" tall... weight 3/4 lb.
Very Good clean condition... some cosmetic heat tone to bottom.
