Firstly, I's like to thank those again who have answered some of my other questions. I appreciate it very much being a newbie. I love these Bund 3H watches. Everything about them is fantastic to me.

Can you please tell me if the caseback pictured below is one that has been seen before and considered correct with just "BW" and the issue numbers?

Thanks again

Here's the front with cut off numbers and slightly smaller circle with bigger 3H compared to some others I have. :
