Need help with value of Early M29

[LtdShooter]

Have an opportunity to buy a older M29 dash nothing SN S193xxx which is in maybe 85% shape give or take a % or two. Have not seen the gun yet but it is described as having holster wear and a timing issue. Has original cokes and is a 6 1/2" gun. Need to know an approximate range for a value so I know what I might offer. Thanks for your time!

Just realized this thread needs to bump over to the 1894 - 1961 category. I'm opening up a new thread there so Mods please delete.
