Wien All White Skye Terrier Austria Dog Figurine

I purchased this beautiful Mint Condition Skye Terrier and would like to know when it was made and how much it might be worth.

It measures 6"long x 5 1/4"tall x 3"wide.  It's marked on the bottom, "Wien" in blue below a blue logo.  Incised above is "Made in Austria" with the letter "L" next to that and the number "1631".

The sticker address label is just a previous owner and I haven't removed the sticker yet.  The detailing is fantastic and I can't find a dog like this anywhere on the internet.  So any information would be appreciated.  I know Wien means Vienna and have even looked up Augarten Dogs.......but Augarten does not appear on this piece.

Thanks so much for your time!
