Before anyone orders anything I think I have the cheapest solution for our required coloured markers for WW1 guns.
I picked these up last Year at the show we attended in Wolverhampton
They are currently available from www.minibits.co.uk for £1 for 30 so I will order some once I have some feedback on how many we really need.
I can easy spray them using my air brush with the designated colours which we require for the guns.
Let me know what you think and how many packs I need to order.
