$1500 price might be slightly high, IMO. For a 90% rifle that's all original, market value is probably in the $1100-$1300 range.
This year I have purchased six 300 H&H rifles. A 1952 Sporter in in 98% condition for $1300. The other 5 all had cut or custom stocks and I paid less than $900 for each of them.
People are typically asking a $1500-$2000 for .300 H&H rifles on GB, but those rifles aren't selling. looking back though the past 90 days of actual sales, I only found 3 rifles which sold on GB. None is an exact match to an unmodified Sporter with 90% finish, but they give you some idea of the prices the market will bear right now for a .300 H&H.
