OKB offers three very similar products, all in 35th scale, for use on a Pz.IV . These items are “return rollers” for the Type 2 (product S35007), the Type 3 (product S35008), and the Type 4 (product S35009). This review will focus on the rollers for the Type 4 (product S35009).
The roller parts are contained in a small zip lock baggie. A paper label is stapled to the baggie which serves to identify the “Type” for which these parts are engineered, and to provide a secure closure so that none of the parts go astray.
