Yes, that is the type I saw in the Czech Republic at the market the summer of 2002, mounted on a very nice looking granite "mountain" with a plaque on it.
Your fine looking model has both the support "cables" in the back. Mine is missing one of them, and the shell loader on mine is bent a bit and the rods for it need to be re-attached to the support base. The side of my marble base looks like it may have had a plaque on it at in the distant past.
I've actually seen a handful of this type over the years since that time, all mounted on the granite "mountain". They don't show up for sale very often.
Congratulations on finding one of these some 50-years ago! =D>
