Another find from Hayle Car boot in Cornwall in 2014. Seen on the table of an amateur antique dealer. It appears that it belonged to his grandfather who had been in the car repair trade at the turn of the 20th century. He had used this in his job doing car repairs and servicing. The seller wanted £12 for it but accepted £4 after a bit of haggling. It was covered in a thick layer of verdigris ('patina') that hid any trace of wording, and it his any trace of what the metal might have been. It was an interesting item so I was pleased to buy it.
When I got home I tried to clean it with Brasso but it had no effect. I bit the bullet and got some scouring powder and with some difficulty started to remove the surface covering and revealed a cooper coloured metal. More cleaning got it to the state it is now in and revealed the wording 'JOS LUCAS LTD - No 33 - BIRMINGHAM'. There are dents and digs from its years of use and abuse but it is complete and would I presume still work to funnel oil. There is a piece of gauze soldered into the wide opening that filters bits out of the oil.
A search of the internet revealed a similar funnel, but made of brass, being auctioned in Sydney with a price estimate of $100-$150.
