General It’s a Fiat but which model

[Hypno]

Does any know which model this little stunner is, sadly the person who sent me the picture omitted to study the info board propped against it.

According to the reg, it's a 1500L - https://www.cardatachecks.co.uk/carcheck/lookup.php

My guess is it is a 509 or 509A, made between 1925-29.
(A quick browse through some old books)
4cyl, 990cc, 22BHP @ 3400rpm, overhead cam! Brakes on all four wheels.

Does the museum have a website? It might list the exhibits.
