Sorry if I'm getting in on this late. But I did just find this site today, and this is my first post. But off the top of my head, this is what I remember on the Pro Modeler series (and what kits I can think of.)
The first ones were the Do-335, A-26, F-102, P-40, P-39, B-24, B-17, and F-117. These were all based on old kits that Monogram had out for years. Some were jazzed up with new sprues with new crew figures and equipment or bulged tires. Some may have had some photo etched bits (the Do-335 I think), the F-102 came with the Case XX wing (the origional kit had the Case X wing. Or maybe it was the other way around.) Either way, the PM F-102 is the same one that was re-released about a month ago. The B-17, I believe, came with a new Cheyanne turret. And the F-117 had the bomb bay and open bay doors added to it. But it may have been missing the PE set that came in the origional molding.
The next one out was the P-51B. It cam out the same time as Tamiya's and Accurate Miniatures P-51Bs. And it couldn't hold a candle to either one. It was the same molding as their 20+ year old kit, except they removed the raised pannel lines from the mold and added strips of metal to the mold to make the pannel lines recessed. In so many words, it looked like crap. They would have been better off leaving the old molds alone. I gripe more about this kit more than any other I have ever bought. All Pro Modeler kits from the P-51B on had recessed pannel lines.
Next up was the P-47N. This was an origional Monogram molding that made it's maiden release in the Pro Modeler box. It's not a bad kit overall. But it does have some fit problems and the pannel lines were not as crisp as other new kits on the market had at this time. And it came out at the same time as the Academy P-47N. And many people opted for it over the PM kit because the molding was crisper and the fit problems were fewer, and the resin people opted to make accessories for the Academy kit instead.
After that was the PBY-5 Catalina. It was the same kit that Monogram released about a year earlier, except the PM kit came with beaching gear.
I believe the next kits were the 1/72 scale kits. A Spitfire, a Bf-109G, a Fw-190, and an Me-262. These were all molded by Revell of Germany, but I don't think ROG ever released them. These were all simple, easy to build kits. Few parts. But the looked good when done.
Then came a long line of Pro Modeler origionals. Bf-110, the Helldiver (with photo etch sheet), Me-410, F-84G ( with PE sheet), and Ju-52. All of them are great kits.
The F-15E was released under the Revellogram label first. Then came the PM kit about a year later with new weapons added and a new decal sheet. The last "in house" kit molded by Revell/ Monogram was the F-86D. And it may be the last they ever do.
The rest of the kits under the Pro Modeler label came from other sources. The Fw-190, TA-154 and Ju-88 came from DML molds. And the P-38 and Stuka came from Hasegawa molds. And I believe they are also going to release the Hasegawa A-4 under the PM label.
The Do-217, I'm not sure about. I think it may be a Revellogram/ PM origional. I have the kit. But I haven't even unwraped it yet.
I know there are some kits I have missed. But this is all I could dredge out of my foggy head. Hope this helps out.
