Back in August 2011 I stated this thread asking if it was possible to repair a 149 myself:
I'm happy to know it's helped others over the years and I've come back to it myself several times as well.
Well, the week of October 13th was a good one for me when it came to acquiring new Mont Blanc products.
On Tuesday the 14th I visited an antique mall that I usually avoid and found a great item which I'll talk about later.
On Saturday the 18th I had some time to kill so started perusing Kijiji for MB stuff. The first advert I saw was from a seller in Oshawa with two 149s for sale
After checking the pictures I contacted the seller who promptly sent a few more pics, and we arranged a meeting. Fortunately he was in Whitby, so instead of driving two hours each way, I'd only be driving 1 hour and 45 minutes
The seller was a pleasant fellow and we chatted as I inspected the pens. One of those pens was a near mint 1990 to 1995 149 with a two-tone nib, brass filler and first generation plastic feed. I'll be posting some pics of that pen later as well.
The other pen was a bit rougher. The nib is an 18C from the 1960s. It had been sent to Koor-i-Noor Canada back in the early 1980s for servicing, so the one piece barrel was replaced with a two piece plastic threads barrel. Koor-i-Noor Stylographic was the distributor for MB products back then.
The nib sadly had lost all it's platinum masking, and had three shallow dents. The piston spindle had been twisted in two. Otherwise the pen was fine
I paid the seller his asking price--$350 for both pens--and started my drive home, not knowing how I would replace the spindle.
After searching ebay and online for parts, I stumbled onto a website owned by Roger Wolfe called Custom Pen Parts.
You all may remember Roger's site, which was mentioned on FPN by Rowbo in this thread started by Francis:
Roger has manufactured MB style helix/lead/spindle screws that match MBs OEM products perfectly.
Not believing my luck I placed an order and after getting some help from Roger the parts were shipped.
They arrived today! I sadly did not have an original MB spindle to compare, but I immediately saw the high quality of Rogers work and indeed his product matches MB's in every way save one--you can buy Roger's parts
Here is Rogers manufactured helix screw:
And fit into the piston, it turns smoothly as if it were an original MB part:
The original spindle had broken deep inside the blind cap. I spent two hours trying to remove the spindle head, with about a hour of that time just looking at the blind cap trying to figure out how to get the c-ring out.
Pliers didn't work as there wasn't enough spindle left to get a grip on.
I eventually decided to use the smallest drill bit I have to drill a hole by hand between the c-ring and spindle head. The head being plastic gave way easily and I was able to insert my homemade tool into the hole and hook it underneath the c-ring.
It was a paperclip with a tiny L bent into one end. This L hooked under the c-ring and using pliers I pulled the paper clip out and popped the c-ring out of its groove.
I'm happy to say it worked very well, with only a few scratches to the inside of the blind cap.
This is the remnants of the old spindle next to Rogers manufactured spindle:
I pulled out my trusty ol' ballpoint barrel that some of you may remember from a couple years back, and proceeded to insert the new spindle, the c-ring into the blind cap.
All went as well as the last time I did this, and the loud and satisfying snap of the c-ring being set into it's groove was great.
The piston assembled:
Next I cleaned the cap and assembled it. I was having trouble getting the plastic gasket and screw into the cap together
So I decided to shish-kabob the gasket onto a skewer and slide it into the cap and pull the skewer out the top, then I just dropped the screw inside the cap, replaced the original clip and screwed everything back together:
Next I cleaned the barrel and screwed in the piston. I used a tool first suggested by FPN member Florence back in July 2011:
WARNING: Do not attempt this unless you're sure about your abilities and you're working on your own pen!
Using a tip from Hari about keeping the blind cap turned down, I got the piston screwed in without harming the plastic threads:
I had knocked out the nib and feed from the case feeder back on the 19th and gave it a good cleaning.
I removed the small dents, and most of the scratches that were just behind of the tipping material. I couldn't do anything about the missing platinum masking.
The seller stated he never damaged the nib, so if this is the work done by K-i-N Canada back in the 1980s, I understand now why MB took over it's own distribution and servicing. One shallow dent was on the left tine just on top of the breather hole, and the other two much smaller dents were what appeared to be plier marks.
I think the nib came out pretty good:
Here is the original one piece ebonite feed:
And this is where K-i-N put the nib/feed in upside down with the hole on the feed opposite the gap on the newer case feeder. I wanted to reposition the feed/nib but the nib had put a groove into the case feeder and I didn't want to try heating it to remove the groove. So I replaced it as it was:
I used silicone on the case feeder threads and assembled the barrel, section and feeder assembly:
And the completed pen, in it's original box:
Well, much of what I posted here was gone over in the other thread. The difference is I've learned more from the experienced collectors and repairers here on FPN. Whereas with the first DIY repair I jumped in with both feet full of hope, this time around I had some confidence to go with my cockiness
Thank you to everyone here on FPN who has helped me over the years with servicing, information and to the MB board for getting me interested in what have become my favorite pens right along side Canadian made Parker Duofold button fillers from the 1920s and 1930s.
And an extra special thanks to Roger Wolfe for producing the helix screws. Your parts made servicing this pen so much easier
