Sheaffer Piston Converter Dimensions

[stefanv]

I have a pair of 1960s Sheaffer Cartridge Pens, one of which is transparent. Both a Sheaffer cartridge (obviously) and a Sheaffer squeeze converter, fit easily. I'm wondering if the slightly longer Sheaffer piston converter will fit. In the clear pen, I can see that there's just a slight ledge to hold the cartridge in place, but there's still another inch of empty space beyond that. Since the piston converter's knob is narrower than the rest of the converter, I wonder if it might fit.

 

Does anyone know the overall length of that converter, and what the diameter of the knob is?

as far as i know, the converter has been designed to fit in all sheaffer C/C pens. some pens, like the compact cartridge, will only take carts, as the inside of the barrel is just long enough.

I just tried a piston converter in two of my cartridge pens that are the exact same model as those in your picture. The bad news is that it does not fit. The metal fitting at the back of the converter, into which the knob fits, is just a bit too large in diameter and the pen barrel will not go down over it. The overall length would be fine, but those old pens are just a bit too thin.

Thanks for trying it and reporting back! I'd almost come to the conclusion that it would fit, based on a side-by-side photo of the squeeze and piston converters that I found. It never occurred to me that the diameter might be too large (since I assumed, wrongly, that the diameter would be the same as that of a cartridge).
