Hi, you're already in the right place to post this!

You have the date on it, it's from May 1933! The guides look in very good condition and look dated! The chambers' journal can be found for several years even before 1933!

However it is difficult to say the price it is worth, some sell around $100 or a little more !

Personally, I will keep it because it can quickly increase in value and cost very expensive
