Need help - Birmingham?

This mark appears on a pin which is a horseshoe with a foxhead. There are 7 gold insets in the pin as well.
Any help would be greatly appreciated!

This appears to be a Birmingham hallmark with the date letter “t” for 1893.

Perhaps this will help as well!

AJC’s mark has been seen on brooches but we don’t know for sure who he is. One possibility is A J Cheshire, a Birmingham jeweller.

How about Arthur John Crocker - the year is right …

Arthur John Croker (not Crocker) has a mark in Culme’s book on London silversmiths. He was located in Bermondsey and was listed as a violin chin rest maker. The punch shape was also completely different, so, in my opinion, not a likely candidate.
