This must be the brightest pen I have ever seen, with the possible exception of the Chilton Clown. The barrel imprint tells me that it is a St Michael pen, made in England. Anything with a St Michael label was made for Marks & Spencer, a leading high street chain store. Marks & Spencer still sell pens today but no longer use the St Michael label. The current offering is a no-name pen which seems to be of moderate quality. I can’t tell with certainty when this pen was made or who made it. As to date, my best guess would be late 30s. The maker could be any one of the major pen manufacturers, or any number of jobbers. It has a Mentmore look but that is probably a red herring.
It’s a pleasure to see such a cheerful pen, especially when you consider that black seems to have been the default choice among British pen buyers for several decades. It has a nice warranted 14 carat gold nib. The clip looks a bit weatherworn but I’m sure I can do something about that. There is a shallow incision running around the bottom of the cap which might imply that there was once a cap ring there. On the other hand, many pens were issued with that incision but no cap ring. Considering that the cap screws onto the barrel very well there seems to have been no shrinkage which would cause a cap ring to fall off. Given all of that, I think the pen is in the same condition now as when it was manufactured.
I think that we may be too serious, at times, about our fountain pens. We need more bright, cheerful, multicoloured pens like this!

Hi Deb,
“I think that we may be too serious, at times, about our fountain pens. We need more bright, cheerful, multicoloured pens like this!” I could not possibly agree with you more.
My most cheerful and very treasured pen was given to me from my mother: Vintage Conklin Halloween from the 1950’s I think. If you want to see what it looks like, there is one on this page:

Have a great weekend.

I had a little bid on this one – on my monitor the cream looked much yellower and I thought it looked CS yellow jazzish. I think CS agreed with you philosophy back in the 30s,
There was another colourful St Michaels pen on Ebay earlier this year, and I was thinking they might make a nice mini collection but it looks like I may have competition

If you look in my ‘Interesting casein’ gallery on FPB you’ll see a picture of my Waverley P5 pen (part of a set) in the same material. CS used similar materials with yellow, blue, green & red base colours, but apparently for some reason they never used this cream version. I don’t like the ‘yellow jazz’ reference, very much a relatively recent Max Davis invention, whereas ‘grey jazz’ was a term actually used by CS in the late 1920s! And in response to Simon’s recent e-mail to me, I would say most definitely not made by CS!

That’s a beautiful pen, Andy. I do like these more cheerful colours.
I think you might have! They are a change from the run-of-the-mill black and patterned pens.
For my two penneth full, I would say it is a Lang pen based on the H65. They used plastics very similar to Mentmore on many of their pens. It has the three propeller image on the lever which seems to have been used by both Conway and Langs and it has a Lang nib. Agree with the age upto aprox 1935.
It may well be, Peter.
