I'm definitely lacking the "eye of the luthier" haha. I thought the purfling was identical and the f holes.. lets just say I have a hard time distinguishing any f hole.
The only historical info I was given on the bass was that it was a 1970's German bass. Looking at the catalog you posted a few months back... the 1971 edition from Hofner; there's a model 5/14 violin shape. It seems to fit the bill... down to the ebony trimmings on the neck joint. The neck is also quite flamed...albeit a fake flame. It is a reddish color with faded yellow warn sections.
I'm no expert, but I thought it looked quite similar to the 5/12 model shown in the catalog...it's a shame there aren't many details to go on.
It just strikes me as odd how difficult it is to find any information on these basses. I've seen a select few Hofners turn up on the web, and most were gamba ply basses. Your five string is the closest thing I've come across to being in the same ilk as my bass.
Product distribution is perplexing thing in the bass world!!
