OK, the 18 set. The black finish is early, the painted finish late. It may be a 68 set, which is late war. The 68 set had letters after the 68 which denoted the wavelength P does Not mean Paratroop, just the wavelength the set covered (I know this is true, as I have the handbook). Canvas cover is rare. Does it have it's complement of aerials around the set?
The 38 sets are Mk2 and were the most numerous British Wireless of WW2. Now uncommon as they were replaced by the 88 set after WW2. Should have a juction box and a webbing carrier with a seperate clip.
I think the 19 set is a Mk3 as it has 3 switches. There should be a power supply and an aerial tuner with it, plus 2 junction boxes (No1 and No2). The B set is intact, which is good, as many had this taken out post-war. Beware if the power supply has a luminous switch, as these are radioactive.
The French/American radio is a BC1000. These were WW2, but the French army started remanufacturing them in the 1960s. Only way of telling is to look inside for English or French writing - American sets are more valuable. British made a similar set in the 1950s, called the 31 set.
Mine detector is American.
The binoculars are definetly Tabby equipment.
Also, if you can put a manual with a set, this will make the item greatly more sellable.
