In thinking about it, I think the Polaroid 180 and 195 I have. When I used them more people would comment on them than even my Rollei. Seemed every familt has cool memories of their father having one or them owning one in their younger years. Of course they were referring to the autopack cameras though a few did mention they had the 180 or the 195 but they tended to be less gushing as they tended to be more into the hobby including the equipment.
Next as for the stuff I've owned would be the Exactas that it seemed many returning service personnel from Europe seemed to bring back with them and remembered fondly; then the Rollei, again, memories form returning service persons. Seemed in the '50s and '60s cameras and stero gear were standard fare for returning service persons to buy before mustering out.
