Stipula Etruria Rainbow Prisma 88 - Grease Behind Piston

[drlilviv]

Good morning - Im an old time FP member on Reddit but this is my first post on fpnetwork. I bought a used Stipula Etruria that looks like it has some grease behind the piston on the acrylic on top of the silver shiny part. Wondering if this is normal?? And if not, is there a way to disassemble the piston unit?

 

Thanks!

It's normal. It lubricates the piston and makes it slide smoothly and seal better. It's necessary.
