I was vaguely thinking of getting a small force of WW2 Poles in 6mm for a few scenarios I want to try. A scoot round the internet found the following suppliers in the UK:
1. IRREGULAR MINIATURES: https://irregularminiatures.co.uk/
Cavalry: 22p/fig (I think)
TK3 Tankette: 44p/model
7TP Light Tank: 88p/model
Early war lorry: 88p/model
(French) 75mm gun and crew: 88p/model & crew
A fairly limited range, lacking mortars and so on, but enough there for a basic force.
Tanks (7TP, Vickers E): 65p/model
TKS/TK3 Tankettes: 50p/model
Armoured Cars & Half Tracks: 65p/model
Armoured Train (Engine + 5 Cars): £12.00.
AA Guns, Artillery & Tractors: 65p/model
Trucks & Cars: 65p/model
Very good range of vehicles and kit, but no infantry. You could always use French at a push.
3. GHQ (through Magister Militum, or for some items Wargames Emporium): https://www.magistermilitum.com/catalogsearch/result/?q=Polish&cat%5B0%5D=60064 ; https://www.wargamesemporium.co.uk/collections/wwii-armour-polish
Vehicles: £2.40/model (in packs of 5)
Artillery & AT Guns: £2.00/model (in packs of 2 guns (towed), 2 guns (deployed) and 2 tractors)
Comprehensive, lovely-looking and premium (luxury?!?) price, as is typical of GHQ!
Not a bad selection of vehicles, very lacking in artillery and anti-tank guns. Not sure what you could use instead…maybe a mix of French and Japanese stuff?
SKYTREX did a range I think, but not sure if you can still
get these. Ditto C&C miniatures.
