programs and projects have been planned and executed to 

completion: 

MEMRA PRODUCTS EXPOSITIONS 

Periodic expositions have been held, with an average of 

nearly 100 manufacturers, in conjunction with their 

representatives, exhibiting mechanical equipment in the 

Baltimore area. 

DIRECTORY OF MECHANICAL EQUIPMENT 

This is the directory of members and the manufacturers 

they represent. It is distributed to a combined mailing list of 

all members and reaches architects, engineers, contractors, 

suppliers,users and manufacturers. 

All listings of Firms and Individuals are “Authorized Factory 

Representatives” or “Duly Appointed Agents.”
