Where do you get the silver cloth in the UK, please?
H Samuel (on many UK high streets) sell one for (approx) £5.
(Been a few years since I bought, so prices may have risen accordingly)
pseudo88: Hope the 75 arrives in nice condition. As some others have mentioned, I'd go for just using the pen, straight away - and then do any repairs or servicing, as required. If it has been in constant use, it may be fine 'out of the box'. If standing unused for years, a simple flush may do it.
When I first started repairing and servicing (my own) pens, I went through a phase of dismantling everything I bought, before using it. I probably wasted 75% of my time! Now (as long as ink flows through it) I give pens an extended usage test, before doing anything. Surprisingly, the simple act of continuous writing gets many pens back on their feet
