The following mark has been shared with me. In Crosby Forbes' work in Appendix III he lists ACAO as a Canton maker, yet gives no mark. This mark for AKOW potentially be the same, but I've never seen a so-called pseudo hallmark with a tree symbol impress. I also do not recognise the first character mark [or what could be a character mark]

Does anyone have any ideas?
