I just bought a double bass from ebay which was advertised as 3/4 size. I think however, it might be a bit smaller.... How can I tell? If I wrote out the measurements, could someone tell me what size they think it is?

Ok, measurements are (all in inches):

Full height(scroll to bottom of body): 69.5
Body height (bottom to shoulder): 42.5
Scale length: 41.5
Upper bout width: 18.5
Lower bout width: 25.2
Scroll to shoulder: 27.5
Width at nut: 1.7

Thanks!
