Diana MGR (sharp casting) 

Posted on the airgunforum.co.uk.

Note: this pistol has an unusually sharp embossed floral casting.

I asked spring air pistols expert Professor John Griffiths whether this might be to do with a new (ie not worn) mold and he said: "I suppose one argument would be that the mold used to make the castings could have got progressively worn, as happens with bronze castings. However,  unlike most metals, iron and steel casting has to be done with sand molds, as the melting temperature is so high, and the pattern is impressed in the sand.  After casting, the mold is destroyed, so a new one is used each time.  I suppose the master could wear out, but it would take a long time.  Casting iron and steel is almost a black art, and even the nature of the sand can affect the result, so it is quite possible that sometimes the parameters are just perfect for a fine impression, and other times not."
