got this beautiful Sheaffer Imperial few days ago
this pen needs some service and i noticed something, Tha -SAC- is DRY ! i dont know if it supposed to be rubbery but in this case its not and this SAC neck is broken and stuck to the COUPLING so im in the process of cleaning the pen im gonna put it in water and soap for a few hours, flush it and do the regular stuff will try to remove the SAC neck away from the COUPLING. any ideas how i should do it ? is the SAC in this case dry and must be rubbery ?
