I’ve had a few technical enquiries of one kind or another about Mentmores recently and that has reminded me that there is very little information about the company online. There are good websites devoted to Conway Stewart, Mabie Todd, Burnham and the Langs pens but nothing so far on either Mentmore or De La Rue.
It’s hard now to tell which pen manufacturers produced the most pens but it’s certainly true that Mentmore was very prolific. If you include the sub-brand Platignum they must certainly be among the biggest producers. Both Mentmore and Platignum made technically interesting pens over a long period and Mentmore pens were of comparable quality to Conway Stewart. Platignum pens were lower cost and hence somewhat poorer quality but many have proved durable nonetheless. There’s an opportunity for someone to do a bit of research and get it online.
That leaves De La Rue as the red-headed stepchild of the British pen world (so far as online information is concerned). I understand that a book on the pen production of the company is in preparation but that’s another matter. We need books on the manufacturers but it’s also nice to have an online reference that can be quickly consulted.
