Hi,
I recently purchased a Dorko Modoso in excellent condition with very little hone wear. It has an 11/16 wide round point blade and cream colored celluloid scales. On the blade it says:
From Best Dorko Steel Solingen Made in Germany
and 88 with Modoso inside of a parallellogram

Are these good razors? How old is it? What is an approximate value?

Thanks in advance,
Patrick
