OKB Grigorov is a Bulgarian company that has been producing resin accessories and after-market bits for several years. My first experience with them was several years ago when I was searching for some embellishments for a 1/72-scale Merkava. I must admit that that was the last experience I had with OKB Grigorov. That was a mistake on my part, and this kit is how I fixed it.
As a member of the Reviewers Corps for IPMS/USA, we have access to several kits and modeling accessories that one might not otherwise have, and best of all, these accessories and/or kits are free if you conduct the review. Anyway, when several kits became available to the Reviewers Corps, I noticed the offerings from OKB Grigorov and thought, why not? Time to see what 'these guys' are up to, and I am delighted to inform you that OKB Grigorov has been up to quite a lot. All of it to a modelers favor. I will skip a full-blown review of their product line and simply suggest that you visit their website.
