Just a little aside to show how collecting can get a little out of hand
This is a fairly ordinary wagon, W4635P Coal Wagon, Higgs London, in the first series or Period One box
This wagon also came in Dark Grey & Light Grey
When they came out first the wagons came with a set of Hornby Dublo couplings, but after about 18 months Wrenn decided to charge 1/6 for a set of couplings and they stuck a label on the back of the box to indicate this
So now instead of only 3 wagons in the collection I have 6, 3 without labels and 3 with, see where this is going?
Period 2 came next, this is when they merged with Tri Ang
There were 5 different coloured wagons issued during this period, Dark Brown, Light Grey, Dark Grey, Green and Light Brown
Another distinctive piece of their production was overlabelling existing box's with different labels as can be seen on the right hand side box
So instead of collecting only 5 wagons I had to collect 10, 5 of each.
Light Grey
Dark Grey
Green
Light Brown
Period 3 came next with only 2 wagons issued during this period, Grey & Green
However another variant appeared during this period and that was a long boxed wagon, where the company ran out of the shorter box for these wagons and then used longer boxes for their utility wagons to box up wagons to fill an outstanding order
Also the plastic inners that protect the wagons are now classified as WA1, the previous inners were plain/unclassified.
So a normal Grey,
And Green
Overlabelling was also common during this period and labelling on one end only cropped up from time to time
So 2 wagons now become 8
And finally Period 4 wagons where only 1 wagon was issued and they had dropped the P prefix from their previous issues, W4635.
But as you can see there are 3 different coloured box's, so 1 becomes 3
So 27 Higgs wagons collected and I am sure there are a couple of varients I missed over the years
