I am searching for a business located in Allentown, PA sometime between 1918 and 1925. I have a copy of a piece of stationery that shows the following information: ANGELL & LUTTS,--- ENGINEERS Heating--Ventilation--Sanitation 2652 Tilghman St., Allentown, PA W.T. Angell, Mem. A.S.H.a.V.E C. W. Lutts, Mem. A.S.H.a.V.E The name of the business is in the center of the stationery and W.T. Angell is on the left, and C. W. Lutts is on the right. W.T. Angell was my father, b. 1894, d. 1964. I have no knowledge of C.W. Lutts, or what the initials beside their names may stand for. I hope this is enough information and not too broad a time span for some kind soul to try to find it for me. Thanks so much, Bruce
