It would have been 2007 at the latest,
I found the date code in my set with yellow claws images, 03307, which means day 33 of year 07 (February 2, 2007) but I doubt now that it contains a figure with yellow claws. Tim, it seems to me your figure is very rare and hard to get. According to some users in klickywelt there was never a deinonychus with yellow claws in a commercial set. The yellow claws just appeared on those deinonychus that were used for displays.
After all, set 4175 has caused headaches to many buyers, see what one of them in Germany got, a previous red amphibian vehicle with a different klicky. This set is from july, 2007. Look carefully at the claws in box, they are green. Anyway, I have a hope that my old set has yellow claws but I will never know, I will keep it MIB...
