The model 10 should be a fun shooting revolver, I had one that I bought at a decent price ($149) and got $350 for it on a trade for a Smith 53 - 22RemJet.
Had to buy another so I bought a round butt model 10 police trade in from Buds guns.
The 637 is a nice revolver to carry, I have the 642 and carry it everyday/allday.
You did good on your trade, enjoy the new toys once the weather gets good for you guys.
