The old and new bit referring to the age of the models not their places in history….
First up with have the venerable Matchbox Sherman Firefly (although this is a more recent Revell reissue. The commander is from Battlefield/ Blitz and stowage from various sources.
Next we have some recent (i.e. last decade) Airfix trucks made with modern CAD.
I had a few technical problems painting these: the oil wash that I put over a gloss varnish to define the recessed details took and age to dry and even then remained tacky until I hit it with a matt spray. For future models I’m going to remix all my washes with higher quality turps and use a better gloos spray and hopefully that should solve the problem.
