To determine the manufacturing date of a MJ Kalashen Trumpet with the serial number 381B, you would typically need to consult a specific serial number chart for that brand. Unfortunately, I don't have access to such charts. You may want to reach out to the manufacturer or check online forums dedicated to brass instruments for more detailed information regarding the serial number's date of production.
