Dan, It's still a few Holmes 600's in my area. I had three of them at one time, a few years ago. Sold two of them, but still have a Petty Blue Holmes 600, that I use regularly. I've also owned several Vintage Holmes 515's, Holmes 525's, one Holmes W35, & one Holmes W45. Once the hydraulic Wreckers came out, back in the mid 80's, these old mechanicals started disappearing, little by little. Some converted to hydraulic wreckers, & some pushed aside, & left unused until they met their demise. Check out my link below, for photos of my old wreckers.
