Here is one of my favorite SDP Brookfield 164's in a fantastic color. I know it isn't listed in they guide but it has been compared to the 162.1 color that is listed and is very similar.

This one is the embossing index [020] with the XO on the dome. So far I have found and have seen these with either the XO or the SN 6 on the dome. If anyone else has seen one with a different SN on the dome I would love to hear from you.

Thanks for looking and I hope you enjoyed this small series from my SDP Brookfield collection.
