The Frederick Post Co. No.1457 Mannheim Trig. This looks to be the same as the Arthur Brown & Bro. 7996A, the F.Weber & Co. 4280-A and the Roos Company SR.109. The Roos Company is the probable manufacturer of all four rules. The rule is also the same as the Engineering Sales Co. No.6004 which accordong to the Slide Rule Museum was made by Acu-Design. I personally support the Roos Company theory but feel free to decide for yourselves.
