You should be able to use any 500 series Bowser with lift off doors. The 575 has hinged doors. There is a four ad glass model that I thought was a 557 but Jack says a 557 is a display pump. The one pictured is a 510 that is a non-computing pump. The 565 looks the same as this 510. One of these would be a good candidate for your doors. The doors look like yours but less moldings and a larger window with sight glass in the face.
