Any Goldmund Linear arm Turntable experts out there?

Here is "some info" as far as the T3F’s counterweight(s) values (145.5 grams and 181.5 grams).

Read somewhere that the earlier T3’s counterweight is 90 grams, but can’t find it to link.

PS:

Can't find a pic of the back of the arm.

Is the back threaded for a screw on counterweight?

The T3 used an Allen screw to tighten the counterweight (I think).

Welcome and good luck with it.

Never seen/heard the "F" version, which is said to be a major improvement VS the sans-F.
