Ken Cavers C600 / C400 Triple Play

Hi everyone! Sorry about the delay but I’ll try to make up for it with a three part series of some lovely pens from one of my favourite pen turners. 


A while back I ordered a bunch of 30s/40s vintage tubes of cellulose acetate in three colours. I sent half to Ken Cavers and half to Jonathon Brooks to be made into pens. The tubes are just that–hollow tubes meaning that they will need end pieces and the limited diameter means they can’t be used for caps as well as barrels. 

The red material is called Burnham Rose and apparently was used by a pen maker called Burnham. No idea–never heard of them. I’m not too knowledgeable about lower tier vintage pen makers but this stuff is really beautiful and I’m sure Old pens made from it would have been stunners in their day. 

Ken did this pen up stunningly with gold trim and black acrylic for the cap, barrel end and section. It is subtly inspired by the Pelikan Souverän series of pens, hence the name. It works really well and has a nice classy vintage look to it. 


The two tone steel broad nib writes fabulously well and is fed by a Schmidt converter. The nib is interchangeable with other JoWo nib units and there’s a high likelihood that I’ll replace it with an 18k nib in the near future. Ken tunes his nibs perfectly so there’s not much of a rush there. 

The second pen is made of black and silver cellulose acetate that is similar to stuff used by Conway Stewart in the late 30s. It’s really flashy looking stuff and the helix seam is really obvious on it. The material was formed in a spiral pattern on metal rods. 

This one is trimmed in chrome and fitted with a number six stainless medium JoWo nib. Black acrylic again and quite similar in proportions to the red pen. It posts well and writes like a dream. Schmidt converter again and on all three pens. Works great. 


As always the fit and finish are absolutely top notch. High lustre on both the black acrylic and the cellulose acetate. Nice weight and balance. Perfection really. 

Last but certainly not least is my C400 in Stylograph Green cellulose acetate that is apparently similar to material used by Stylograph pens in the 30s. For some reason this material is more expensive than the other two even though these rods are slimmer. Anyone have ideas as to why?

Due to the size restraints with this rod the pen is fitted with a #5 Bock nib in medium and, as always from Ken, writes perfectly. It’s a small fen but still feels nicely balanced and comfortable in the hand. 


Gold trim on this one and I think the clip is the same used by Bexley on the Jitterbug pen. Nice Art Deco look and works really well. 

Fit and finish is perfect. The converter rattles a tiny bit in the pen due to the size of the section–limited by the barrel material diameter.

And that’s it! I was going to release this as three separate posts but the pens have so much in common this is probably better. Thanks for stopping by! Be sure to check out Ken’s site
