Polish vehicles in 28mm for early war period

[northtroll]

I'm starting a brand new project involving the early war forces of Poland. One obstacle I have come up against is that of military trucks and motorcycles not being available. My thoughts are just to use whatever I can that looks "close enough". The unit in particular that I want to build up is the 10th mechanized in their black leather coats and Austrian Stahlhelms. I know Polish motorcycles were fairly large, but would the German bikes offered by Black Tree Design work with some alterations to the riders? As far as I can tell nobody makes a 28mm makes a Fiat 508 0r 621 truck model. Any suggestions/help/advice?
