R-283-C BRUNSWICK narrow tone arm part

R-283-C BRUNSWICK narrow tone arm part. The reproducer portion of this tone arm part has been thinned to easily accept a Brunswick ULTONA reproducer. The built-in weight control will have to be transferred from your broken narrow tone arm part. The center axle hole may have to be enlarged to accommodate the shaft from the larger portion of the main tone arm. NOTICE that the control pin near the center axle hole is there (many are broken off). This entire narrow tone arm part is of pot metal construction.
