Heritage 1912 Disassembled!

[siamackz]

I received a Heritage 1912 for repair recently. I noticed there isn't much information out there regarding how to disassemble the pen apart from this article by Reed_Thoughts that helped me with some ideas (link) and a video that shows re-assembly (I can't seem to find the link now). So, I thought I might add to these ideas. Here is how I opened the pen up ...

Kudos to you and your bravery for attacking this successfully! The inner works don’t have the simplicity and elegance of an old fashioned safety pen or a practical piston, bit it was the most unique and interesting design that MB came up in years.

Thank you! Its basically a cartridge filler - disappointingly simple, but I suspect quite economical for MB to produce

Hello:

Thanks again for this usefull thread.

Thanks to its explanation I have been able to confirm that this model carries a captive or hidden converter type filler, and not a traditional piston filler as in other models of this brand.

Regards.

Did you get it working?

Shame they put so much premium on it then.

 

I love mine, but I am tempted to straighten the snow cap on it. I believe it is a special tool to get in and losen the nut in the cap?

siamackz and jagwap: How I wish that they could have made just the old fashioned safety pen, with resin/ebonite body and metal/ebonite inner works. It would charm many vintage MB fans (and probably frustrate sales people trying to sell to tourists ).

 

I have come back to this thread multiple times to look at the disassembly. Thank you again for sharing, siamackz. To put a piston (or really a c/c) AND helix safety mechanism in one pen is just too much. MB did the best they could with costs taken into consideration.

You need remove knob first instead of removing barrel and section. Section is very thin and can be easily damaged.

 

First, pull knob out, you see two slots and then using a locking plier to hold the two slots and turn out the knob. The knob has reverse thread. Now you can easily pull out the whole pen unit.

Buy a smallest locking plier from hardware store, such as homedepot. Use rotary tool to tape down tip to 2mm thick. Use this to lock down two slots. Find a piece of fake leather, hold knob using another small locking plier and turn.

 

The whole process won't take you more than 60 seconds.

Hi dbs, are you talking about the cap? Or the barrel? I am assuming you are talking about the cap because the barrel didnt have any reverse threads.

Sorry, should say end cap or knob, you didn't dissemble, at least from your photos.

Ah, got it, you mean the turning knob. Very nice! Thanks for sharing!
