And another promesing Dio from Hellboy.
As far as I know the white cross is for the Polish campain right.
The crews put often mud at it, because white are so visible so it look sometimes yellowish at pictures.
For the France campain it was not so common but I saw at ebay some pic with this white cross and a german text that indicate the vehicle to the Fall Gelb. Now it is up to you.
The 251 look well done. The Dragon kit is a true improvement to the aged ESCI one.
I could be wrong for the MG but both look to me as MG34. That is Ok for the timeline then.
I like the idea with the brick, pavement (puh, lot of work!).
That some of the big red brick are in different angle is a lifelike aspect.
I can only put me in the row of Susofrick with the dandelion.
Wish you a van Gogh hand again during painting as your past Dios.
