My serial number is 5U 4741 and was told that it's a 1947 D2. Based on the previous sequence of numbers it sounds like it's much newer than 1947.

"I also joined a year ago. had been on here a couple of times as a non-member and found the info very helpful so I got a one year subscription (not very expensive at all) to try it out. I really like all the resources on here so I just got a three year. I think its a very small price for what you can get out of this site."
