In February 2009 I had the very good fortune to be given what was described by the former owner as some very old Meccano. There were two sets and one turned out to be a 1912 Number 4 outfit more or less complete but with extra parts not included in the original set. This came in a rather worn box (shown left), however many of the parts were in a pristine condition. Pretty good considering the set is now well over one hundred & ten years old.
Rather than just use the set as an item to display I set about choosing a model from the manual one of the best was the "Swiveling & Luffing Jib Crane", a number 3 outfit model.
Derrick cranes of this type were very common in yards and wharfs and from the earliest days of Meccano this type featured in instruction manuals. Over the years there have many different types published in the manuals from the smallest outfits to the largest. The box label shows a similar but simpler version of the crane.

At the time the set was made the Meccano system had a fairly small range of parts, these were finished in bright nickel plated steel with the gears and wheels made of solid brass. The bolts have larger heads and are longer than the modern ones see picture below right. The brass parts that have tunnel fixings. An illustration of this method of fixing is shown on the left. The tunnel fixings keys were first used in the 1901 "Mechanics Made Easy" sets but these used a grooved rods that helped secure the wheels and clips on the rod. These later ones date from the introduction of Meccano in 1907 but without the grooved rods.
The set included two small contrates but unlike the other brass parts these have tapped bosses. For a while sets had a mixture of key fixing and tapped bosses this set would have been produced at that time. The brass key fitting parts are marked with a 1911 patent this refers to the method of fitting the centre boss. By 1913 this method of fixing was made obsolete by the use of the much better tapped bosses.
The construction was straightforward but using the larger bolts (described as "machine screws" in the manual) seemed strange after a lifetime of using familiar smaller bolts. The Instructions describe what you can clearly see but not what you cannot. The gear box illustration is completely misleading and I found impossible to build. What appears to be the same gear box in another model is shown clearly and shown constructed in a way that will work. One thing I found out is that the large bent strip is quite different to the double angle strips that came later it must have been 3/4 " high to clear the contrates and clips as they are mounted on a rod that goes through this part. The part unfortunately was missing from the set and I have made a replica by folding a nickel 7 hole strip just beyond the second and sixth holes to give greater height.
It was quite obvious that the crane had been built before with the parts as the four of the 25 hole strips were bent in the same way as those in the illustration so I had no need to bend them.
The set came with an original hank of blue cord but I did not want to cut up this, at the time 100 year old relic so I have substituted more modern red cord. There was a shortage of the tunnel fixing keys 22 being needed for the model I had only 13. Where the keys are not required for fixing the brass parts I substituted modern spring clips. The set was provided with small wood screws with which your model could be secured to a solid wooden base but I have used other screws of a similar size to fix the model to a nice old bread board I found in my garage possibly as old as the set.
I think it is an excellent model, each function is controlled by turning a handle one each for, Swiveling, Luffing and hoisting. Although hand operated there is a simple sliding gear box for raising or lowering the hoist. The later version (circa 1914 ) of the model dropped this function. The early style Pawl and gear works well on the hoist.
I am sure the Meccano Boy of 1912 who originally owned this set would have gained a great deal of pleasure in building and operating this model just as I have. The 1912 Number 4 outfit used to build the crane is shown on the right.
Doing a bit more research May 2021 I realised the set must have been produced in 1912 because the flanged sector plates have USA patent Nov 18 1912 very lightly stamped this was when the patent was granted. So this was a short lived set still using the tunnel fixings but with two small contrates with taped bosses during 1913 all tunnel fixings had gone replaced by taped bosses.
