Bruce,
I have a 201 in 20 gauge with a straight stock, this was my go to gun for game farm birds this year.
They were made by the same company as the repros it appears to be a hybrid with some Parker features some Winchester 23 features, and some of it's own. The frame lock up and top lever are Parker, however the frame appears longer and there is no Dolls Head rib extension.
There are lightning cuts on the Water table. There is also a joint check on the barrels and the cocking is different from the Parker. The vent rib is not like the one on the Winchester 23 it looks built in not applied. The forend latch is from the Model 23, and the ejectors look to be also from the 23. The trigger looks like a model 23 and the selector is built into the safety, it is automatic.
I love this gun and dub it "The poor man's Parker Repro!"
This thing POUNDS Pheasants!
Let me know if you need any other information.
Regards, Scott
