Is this Alvis Hare orginal?

The hare is renowned for its acceleration and turn of speed so was a natural choice for a car mascot design. Alvis Cars adopted the hare during the vintage period to reflect the performance of the immortal 12/50 model.
Many different mascots, from many manufacturers, have featured the hare. The quality very variable from poor design and material to being sold in solid silver by the top London jewellers. The hare could be sitting, running, head cocked, one ear tilting and more, then there was the association with the hare and tortoise, made as mascots also.
The rabbit was copied too, and an interesting one was specifically for the Austin Seven (and other small cars). The real-life comparisons between the rabbit and hare here were obvious - Alvis owners can get very annoyed if their mascot is ever called a rabbit, perish the thought!
Chris’s mascot above is from the 1930’s. The ‘LL’ mark is of Louis Lejeune who took over the Lejeune business in 1933 after his parents Augustine and Emil. Today’s company use different wording and logo. It was an accessory mascot, not used by Alvis themselves (though an owner may have requested one just to be little different). Today, many rabbit and hare mascots for sale incorrectly associate Alvis in their description.
Jenny’s is also an accessory mascot. I have seen a few similar to this one. Simply sold to decorate a car, a personal choice of subject and design. It is not marked by a sculptor or company which generally meant a lower cost item at the time. To the collector Chris’s mascot is the more desirable but it all comes down to personal taste.

I have this brass hare with red painted base, presumably a car mascot which belonged to my father ~ inter war years I think. Can anyone throw light on the origins of this.

There have been, at least, four designs for the Alvis hare. The earliest is often called 'Big Paws' (or 'Fat Paws') for obvious reasons - his feet are very broad, and the ears are longer and broader than later mascots, and the face is somewhat artistic/naive and not accurate to the real thing. Then came a hare with mid-size paws, the face again questionable. The third was alloy (the earlier were brass), now the paws were narrow and the face noticeably different, more like the living animal. Usually the first two have their legs pointing forwards and downwards, ears erect. The third has his legs more bent at the joints. Note though that all can have their legs and ears bent over the years, even to having one ear, or both, tipping over. They vary in height. The later hares, from 1928, were made by A E Lejeune and are marked AEL on the base. Big Paws is usually brass, sometimes nickel-plated, never chrome, and rarely signed . Some 1920's ones are nickel-plated, the later 30's ones being chromed. Further confusion is because the Alvis Owners Clubs have had the mascots reproduced, even in the recent past, and further 'unapproved' copies do surface. The mascot company Louis Lejeune still today manufactures the Alvis hare mascot, even in gold-plate!
