Question about a heirloom Tomato

[Medbury Gardens]

I grow a large number of heirloom vegetables for seed,in which i have two New Zealand tomatoes that are grown each year.One of them was brought to this country by some Lebanese immigrants many years ago but its original name has been lost to time,we simply call it "Lebanese".Its a early tomato to ripen,mid sized and has excellent fruit set capabilities even in my hothouse

Anyone recognise it ???
