No. 1 Forend

The Semi Beavertail forearm is the Semi Bevaertail forearm whether installed on a "B", "AB" or a "V". The only differnce is the inletting for the different barrel profiles. There is no "V" semi beavertail in terms of exterior dementions compared to a "B" or "AB" The only difference at any point in time is the barrel inletting for the different barrels. It's one of the reasons the "AB" sort of looks awkward or off balance.

The Semi Beavertail forearm changed exteriorly over time. The original version was quite rounded and the tip was very round. By the time yours was made the bottom was flatter and the tip was a bit squarer. By 1978 it was quite flat on the bottom and the tiip was quite square. The only change since then is the change in the angle of the front of the reciever in 1984.

Unless you are very familar with the variations or just happen to have all three on hand to compare the easiest way to tell would be to look on the inside of the forearm. There should be a date stamped in the inside bottom of the barrrel channel. This is the day the first coat of finish was applied to the forearm. While not definitive it is probably the best indicator you can find to show when the forearm was installed.

Check the Clayton book, you are looking for the "second style".

Just saw this, take a look at GunBroker auction 203297385 pictures #2 and #4 do a very good job of showing the rounded tip on the forearm and most of the other features. Your's should look like this one to be correct for age.

Thanks, I looked at those picture on Gunbroker. On that forend, there is something that looks like a screw head just ahead of the hole where the mounting screw attaches the forend to the receiver. My current forend does not have this. What is it?
 
Nothing you have or need. If I had to guess they installed a Hicks Accurizer or drilled the forearm hanger (What we did before the Hicks existed) and tapped it for a screw to adjust barrel tension. That screw is usually left inside the forearm and doesn't show and is adjusted with an allen wrench through a small hole in front of the forearm screw..

In this case it looks like they extstended that screw out far enough to make it much easier to adjust the tension/pressure on the bottom of the barrel.
