Aug should be the Fritz 0.9.3 ---- 186.786KB file version like mine.
I pretty much do all my parts that way now. I find a part with a view I like, save it as new, export, unzip, take the svg I want and mod it, and load just that svg into my new saved part that is derived from something similar. I mix and match svg from multiple parts all over the place. You can tell old svgs from new with white silks, or the coppers are separate instead on one inside the other.
