Modern Toys - TM Trade Mark Japan - Toy robot Japanese Tinplate & Battery Operated LION TARGET GAME completo in Scatola PERFETTO with GUN - 1950-1960 - Japan

Vintage toy made in TM (Trade Mark Modern Toys) JAPAN from the 1950s-60s. Original with box in wonderful condition and functioning.
Automaton lion robot to which the dart must be fired with the tin pistol.
When it is struck "it roars, moves and its eyes light up".
The Lion is in MUSEUM condition; perfect, it looks as if it just came from the factory.
The pistol is working and shoots very well.
You need to strike the button on the lion's side to activate it.
The button to press should be lubricated because firing the dart does not apply enough pressure to activate it, whereas touching it with a finger activates it immediately.
I asked artificial intelligence how to solve the problem and it told me that it is a matter of the ancient lubricant that has dried out and should be lubricated again.
We are talking about an extremely rare TIN TOY, especially in these immaculate conditions.
The package even includes the INNER packaging, the Lion, a Dart, and its TIN pistol.
Working toy: I am attaching a VIDEO link from my YouTube channel where it can be seen in FUNCTION.
