Believe they were used at several hotels in the mid-60's but primarily an equipment supply company. No true attribution can be made to being used at any specific location to warrent listing same. No more than a dollar bill can be attributed to a given casino or card room.
At least that is my opinion. The name in the door means VERY little to me.
Hope this helps.
Wising you enough,
