Nice job!!!
I too own a Cav.51, and it was my 2nd machine.... and I tell ya, I LOVE the look of it! And I tell most people that I think it's my fav. machine!!!! I just love the full redness of it, the large embossing, the classic look, and how mine has the step by step lettering of how to buy a coke!!
I think i posted this pic up before somewhere here, but if not, here it is again, along with my Pep81 and in the back my 44.
IF, and thats a big, IF, I were to ever restore a machine, this one is at the top of my list, yet it's a GREAT machine, as it's been an indoor machine it's entire life (Im only the 3rd owner, as it was originally at a ad agency office, then when they shut down, the guy I bought it from loved it so the boss gave it to him for all the hard work over the years, (and the fact that the boss sat on his guitar at the closing party and broke it lol) and then when that guy retired, he sold it to me!
Cheers!!!
