Old Scotch?? Dewar's White Label and White Horse
 

Unfortunately I "may not post attachments".. I'll send them to you in an email :(
but....I was just recently given two bottles of scotch, unopened, that were found while cleaning out an elderly relative's home. Dewar's White Label and White Horse. I have no idea how old either are and am more curious about their age for interest's sake, than for any interest as to their worth; I'm sure looking forward to cracking them open once I find out!
Photos attached; both have a US Federal Tax Seal on them (Series 112), though neither have any other dates. The bases have writing embossed in the glass, but other than the name of the respective distilleries, nothing else is very clear. The Dewar's does have a number behind the label "-70 773".
Any ideas?
