Is there Repair Instructions for LIONEL 152 Crossing Gate anywhere?

I do not have the repair instructions, but I am wondering if there is a difference between the model released in 1940 and the model released in 1945? I have repair instructions for most post war models such as the  252 Crossing Gate, but the instructions for the 152 is not included as post war. I am thinking that perhaps what you are looking for is located in a pre war collection of repair instructions (which I do not have).

If I am correct, the source you need is "Greenberg's Guide to Lionel Prewar Parts & Instruction Sheets"

Thanks John in California. I managed to repair the 152 without the instructions. I believe you're correct the 152 is a pre war

REVIVED,,,I have one needing repair, were repair directions ever located? I am going to try the tube next.

Thank you, Greg
