Greetings, I have a 1943 Cement Laundry Tub from my grandfather, I am looking for a pair of strainer baskets for this tub. It is a double basin, the old strainers drained into one piece then on to the trap. I am looking for anything that will work for this tub so I can save it for regular use. The cement is 1 1/4" thick, the opening for the strainer flange is 2 1/2", the drain opening (center of flange opening) is 1 1/2". I have been unsuccessful in locating the hardware for this tub. Please advise. Thank you
