Deutsch-Bonnet naming can get very complicated as they often modified existing/previous bodyshell and re-designated the models.
This DB can also be know as an LM 60, if that's the name you're looking for? (as raced at the 1960 Le Mans 24hr wearing numbers 51 - which didn't finish, and 52).
I dealt with the entry of thus actual car to the Goodwood Festival of Speed a few years back (you can see the Goodwood sticker on the fender) and drove the car very briefly, which was a dream come true. The car was described as a DB HBR5 60/61.
