This appeared on Craigslist, certainly one of the last undiscovered of its type,  a 1929 Deluxe Eight 645 service truck wrecker conversion of a Holbrook Inside-Drive Limousine body: https://worcester.craigslist.org/cto/d/cherry-valley-1929-packard-645/6775956626.html   I have no interest or stake in its sale, just thought to bring it to general attention, an interesting historical vehicle.
