Is this an Austrian bronze please?

I should have had "Austrian Vienna bronze" in the title and can't edit. Poop.

The dog is the same size as one sold in August on eBay (picture two, with the eBay description, but other photos had expired.) I can't find any marks on mine and wouldn't know where to look. The third dog is from Mutualart, looks the same and is described as a Vienna bronze, but there's no more available info.

My dog is 4 inches x 1 3/4" and with the cart measures 5 1/2 inches long. The wheels turn.

That's as far as I get, apart from warnings of fakes and that novices should steer clear. He might have to become a pen wipe, @kyratango

 

Looks like there might be a mark on the inside of a hind leg.

 

I've gone squint staring and don't see marks on legs. There's that circular mark at the dog's ribcage, but I think I am clutching at straws. The dogs' collars are different. The other two appear to have a st bernard-style brandy barrel. I don't see this as being a big deal, however, since no dog should not be draying under the influence. Mr Buchinger's marks seem to be varied and hard to find. These are some I found on the internet. Sigh!

Good night.

 

I see: VIENNA
and something like SLA. or SLB. below it

The number may be 610

YAY!!

 

Unfortunately, @antidiem, those are marks taken from the internet so I'd know what I was looking for. But thanks for the enthusiasm!
