If my memory serves me right, the Cosmic Cogram 4000 MkII uses a Jelco SA-50 tonearm. You should be able to easily source parts for the SA-50 online as it was a high quality mid-range priced tonearm and hence very popular with manufacturers of mid-range turntables in the 1970s. There are SA-50s that appear on eBay for parts and they could be a good option too. Nevertheless if you are looking for the specs of the SA-50 weights, here goes:

• Counter Weight - 119 grams
• Bias Weight - 2.84 grams

You can ask a local machine shop to turn one in brass for you. A digital scale will be required to use in conjunction with that to set the desired VTF.
