effective mass of Jelco tonearms

Can anyone help with the effective mass of Jelco tonearms with detachable headshells [I believe SA 250 or 750}?I've found conflicting values, including 18.5 gms, and other values. Is this without or with headshells, and if with headshells, what is the weight of the headsshell?

The head shell on a SA750D with a ZYX R100 cartridge mounted with 2 screws weighs in at 17.97 gm.

The R100 is listed on ZYX site as weighing 5 gm, leaving a net of 12.97 gm for the head shell including the mounting screws.

Best of Luck
