I have a Lyman that is made by Euroarms. I think Lyman used more than one manufacturer just like CVA used to use ASM and now Pietta but they will likely be marked CVA.
My observations on Remmie makers:
Pietta=good guns, heaviest built, thickest grips, post front sight, meatier frame, best prices.
Uberti=maybe better guns (not seen the upgraded newer Piettas however), lighter frame (less meat around the barrel), dovetail front sight, narrower grips
Euroarms=quality like the old Piettas, lightest I've handled, smallest grips, Uberti cylinder will fit a Euro,dovetailed front sight
Spanish=handled only one, resembled a Euroarms, light frame
ASM, Pedersoli, Hege(?) , etc= don't know
