Montblanc Leonardo Ballpoint Refill - Help Requested

[gmax]

I’m having difficulty with the fit of refills in a Montblanc Leonardo ballpoint.

 

An older “Pix” marked refill works, and allows the click mechanism to work perfectly, but when I fit a current production refill, the point barely protrudes from the nose of the pen. Maybe the recess in the refill end cap is deeper on the current product refill?

 

Can anyone please suggest a fix for this? Any help will be appreciated

Im having a similar problem with newer montblanc refills and an older type s ballpoint pen; the refill appears the same externally but the central indentation in the top of the refill is deeper than the old refills, allowing the propelling mechanism to sit deeper and the point does not extend far enough out of the barrel. Any suggestions?

The dimensional difference in the old vs new recess is very small. I snipped a very short length off a wooden cocktail stick - short enough to fit sideways in the plastic recess - and dropped it into the recess before reassembling the pen. The refill now fits perfectly, and I can live with the fiddliness, given how infrequently I will need to change refills

Thanks, I took your idea and found an elegant solution- a standard plastic advertisement pen refill is precisely the right diameter to fit the recess- I trimmed the plastic refill to get the correct length and used the remaining refill to tamp it into place- the montblanc refill fits the pen perfectly and the refill will still fit newer pens without removing piece. Friction holds the piece in place so it wont fall out if refill is removed from pen.

That is an elegant solution - thanks for returning to share it here
