Guinness Mystery?

[Back Yard Brewer]

I went to garage sale yesterday and stumbled across a couple old Guinness bottles. Being quite partial to the old Guinness I bought the two old bottles. My question is, can anyone shed anylight on how old they may be? They are 185mm high and 50mm around the base. On the side of the bottle at the bottom it says "Guinness Is Good For You" On the base there also the numbers A1722. The glass is quite thick and there are know labels on either bottles.

From a quick look at one of my beer history books, they look like the 1959 miniature or "Lilliput" bottles made for the Guinness Bi-Centenary.
I could be very wrong as Guinness has used thousands of different shapes over the last 100 years, there was a similar shape around 1890-1911, but those look a bit taller and were a half pint.

Hope that helps - just dont quote me on this one, there are people out there who are experts on this sort of minutiae if you want a better answer try a bottle collecting website, there are sure to be plenty out there.
