Johnnie Walker Age?
 

I have found and old bottle, with 501, 16 on bottom. John Walker and Sons Kilmarnock Scotland on front.
Any ideas on year?

Thanks for the photos, we will see if we can have this bottle dated for you!

JW's parent company - Diageo - tells us it's really difficult to accurately date a bottle that has lost all its labels, but from the embossed writing on the back of the your bottle, it was dated from the late 1930s or 1940s. ;)

Hi Jojo, from the neck finish for the cork I reckon this is from the early 30's rather than the late 30's. From the early 30's JW [like most whisky companies] went on to a stopper cork rather than a plug cork and this looks like a plug cork neck.
The William Teacher company invented/designed the stopper cork but the patent ran out in the early 30's and most whisky companies went down that route. You may still see some old Teachers advertising from that time telling their drinkers to throw away the cork screw.
