Found an antique ship in bottle dated 14/9/25 in a thrift shop in Cape Town

Friendly greetings. I like to trawl markets and thrift shops here in Cape Town for cool little objects and I picked this amazing ship on a bottle that seems to be dated from 1925. The glass is clear it and has a beautiful coastal diorama painted behind. I'm amazed at the intricate rope work and there's even another smaller boat in there as well. The bottom of the bottle is marked: A 4 E / C 6 / UGB and its sealed with cork and wax. Incidently, I paid R80 which converts to just less than $5. 

I thought this community forum might appreciate the lucky find and hoping the experts here might be able to share any extra info.
