Thanks in advance

Thanks for the response, I sent you a PM, but I am not sure if you received it at all.

Here are the measurements:

I grabbed my digital calipers and and the outer diameter measures .982" or 24.98mm.

Where can I get this "S&J Bayonet mount" from? or do you have something for me?
