The guitar you have, an X-220 with serial # 1012 is from the first year that Guild started to produce guitars in New York City, which was 1953.
It was part of a line of instruments that consisted out of the X-100, X-200, X-300, X-400 etc. These models all came in a sunburst finish.
The 'blonde' finished versions were called X-110, X-220, X-330, X-440 etc.
The X-100 (X-110) was the non-cutaway model with 1 pickup and the X-200 ( X-220) was the non-cutaway model with 2 pickups.
There is a small chapter about these guitars in 'The Guild Guitar Book - The Company and the Instruments, 1952-1977', which I published some time ago.
By 1954 Guild had established a completely new line of guitars and most of the 'early' models were discontinued.
Since these models were only made for such a short period, they are quite rare on the used instrument market.
