u/Feeling-Tell-9904

I'm looking to put together a 1914 german infantry impression. I want it to be cheap without sacrificing quality. Does anybody know where I can get a, a good quality leather pickelhaube, and b, a good quality belt with a prussian belt buckle included if possible. Also a good replica of the model 1907/10 feldrock uniform with the trousers and tunic included. Can be officer or private, or both.
