Simpson 260 2

[GJBuksar]

I recently purchased a Simpson 260 Series 2 and the face is much different than the normal. What’s different is the red lettering and the left and right control dials. I thought the dials. I have seen a YouTube video where I have seen this exact model but yet to receive a response. I have attached a link hopefully to find out more about this version. https://www.ebay.com/itm/Simpson-260...-127632-2357-0
