Hi! My name is ***** ***** I would be happy to help with your wonderful tiger and crocodile group. Thanks for the excellent photo, I can see exactly what you have.
Can you very kindly look under the belly of the crocodile and see if you can see a square foundry mark seal and another mark close to it. If you can get a close up photo of this, that would be excellent. There may also be another smaller square mark under the chest of the tiger.
Also, how long is the piece roughly.
Many thanks and wait to hear,
