I have a DA 38 with matching numbers on the butt plate and cylinder of 282825. One like it sold on GunBroker last month that was identified as 5th model with numbers starting with 44xxxx. The rev. looked just like mine except it has a 5 inch barrel and mine is a 4 inch barrel and of course my numbers are lower. Any idea of when it might have been made. I have no desire to sell it. Thanks
