The Remington Model 11-87 was manufactured from 1987 onwards, and to determine the specific manufacture date for a particular serial number like 444542, you would typically need to consult Remington's serial number lookup resources or contact their customer service. Serial number databases often provide information based on the specific range of production years for each model. Without access to those resources, I can't provide an exact date for that serial number.

That is not a serial no of a Remington 1911A1 they stopped in 1945 with 2465139.

RW isn't part of the serial no, it stands for Remington Works 1915
To determine the year of manufacture for your Remington 760 Gamemaster, you'll need to reference the serial number against Remington's production records. Remington began using a specific serial number system in 1921, and the first two digits often indicate the year of manufacture. For precise information, you can consult a Remington firearms reference guide or contact Remington directly with your serial number.
