Dunhill Bent Marked 53/1 Dating Question

[oldguyoldpipes]

Hello All,
I am in the process of documenting my Dunhills and ran into this question:

I have a Dunhill Shell with the following markings
53/ 1
Dunhill Shell (over)
Patent No. 1341418/20
Made in England

Because the stamping runs into the Shell Briar, I do not see a year stamp after either the word England or the end of the patent number.
However, I am suspecting that they possibly stamped the year date after the shape number since that is the only flat surface on the bottom of the pipe.
If I am correct, then the year stamp is a 1. Using the pipephil.eu dating matrix, it seems to me this would date my Dunhill to 1941?
I have attached pics for reference.
Any help would be appreciated.

Nice pipe!
Looks like this one was finished AFTER lunch that day.

No, th e1 after the shape number refers to the Inner Tube used. There isn't any date mark I suspect. However, the answer to your question, I believe, can be found here,

Thank You very much for this information. I only have 3 bent Dunhills, a 1929 Bruyere, a 1968 Shell Hungarian and this Shell. With this information, since the stamping is exactly as in the article and I do not see a year stamp, I will, for now, consider it a War Pipe.
