Here is an example of a 105 Series Alfa Romeo Toolkit circa 1965 – 1969. This toolkit is based on toolkit samples I have acquired over the years and to explain which toolkit is correct will not be entirely accurate because I have seen a couple of variations of it. Most of the differences I have seen has been primarily on the screwdrivers or the bag itself. Early backs appeared to somewhat dark green with a strong black tint to them, some had two snaps but I believe these were the case to the very late series toolkits somewhere around 1969 or so. 1971 toolkits bags were black with a single snap and a very low-grade canvas if you would like to call it that.
The reproductions I am making are for the 1965 – 1969 periods and these should satisfy the discerning connoisseur. Meaningful comments and historical accuracy that would enlight others on the subject matter is always welcome and highly appreciated.
