Thanks for posting! I think this operator could be either our 39-090 or our 39-188, however the defining factor between the two is hidden in your picture. Which of these is closer? If you can't tell, can you show me the full arm? That will allow me to decide. Thanks!

The arm is still partially obscured, so it's hard to say, but I think that our 39-188 & 39-197 could be a good match. Again, it's hard to tell, but take a look at those and let me know if you agree.
