Was using pens a lot more before, but my son started to ask me to sketch random things. I tried to pull out my old pentel side click (quicker clicker 0.7mm) from 07 and the clutch was worn out (could reliably hold the lead). So I grabbed a mars technico from my dad, then bought a rapid pro 2.0 2mm, then got a kuru toga advance upgrade. Felt I needed a titanium mech to match my titanium bolt action maxmadco pen, so I got a modern Fuel (0.9mm and 0.7mm mechanism) Then saw a great deal on the kuru toga metal. All within about 4-6 weeks. I may have a problem with my hyper fixations.

Inherited this system from my dad. He had it custom built in 2005-2006 he does not have the shop's contact or the build specs. Need help identifying parts, ideal use case, and value (parts vs whole).

Looked up magenta but their website doesnt have anything that looks similar.
