I have a White Rotary 43 also. The best i could date it was that the crinkle finish 43's were made from 1942-1949.
I love my mchine, but I got a very good deal on it.
Beauty is in the eye of the beholder. If you like it, want it, lust after it, go for it or you will regret it. IMHO The amount of $$ to spend is up to the beholder.
