Lionel 74A Brush for the SL-45 Brush Plate - Early 700 1915-1916 - The 74A motor brush is used exclusively with the SL-45 brush plate as used on the early Lionel 700 0-4-0 electric box type locomotives (which includes some #150 locomotives) produced by Lionel during the 1915 to 1916 period. Finding a 700 in good working condition is extremely rare. Finding replacement parts is even more so. These brushes are custom made and sold in pairs only, maximum 2 pair per customer. The SL-45 brush plate, or its brushes, are available by request only.
