Considering its relatively low ISP, the Truax TR-1 steam rocket might have been in the category of what today would be called LPRs (Large Model Rockets), in the "borderlands" between model rockets and HPRs. With today's engineering, I think steam-powered model rockets of the size of the Vashon/Estes Cold Propellant model rockets are feasible; like Truax's steam rockets, they could have calibrated-pressure safety valves (like those in pressure cookers) to prevent steam explosions if the water in the rockets was over-heated.
