Thread: Razor mfg time period??

I have a 7day set mfg'd by Hill & Son, 4 Hay Market S.W.
The set is in an oak box with a brass plate attached to the lid stating that it was presented to one C. Welch in July 1923.

My difficulty lies in the fact that these razors must have been mfg'd prior to 1891 since that was the year when an international agreement was reached that all products would have the counrty of manufacture stamped on them.

Neither the oak box nor the razors have the city or country of manufacture stamped on them. My question then is may I safely presume that the set was made prior to 1891 but was not presented to the recipient until 1923?

Also, this set has never been used, never been honed and the wedges are definitely made of lead which increases the possibility of manufacture back to the 1800's. And under 40x illuminated magnification, the pins do not appear the be backed with washers. Just pins peined over.

Any thoughts will be very much appreciated..............
