Agreed - truth be told, there are likely very few 100% original advertising clocks in the collecting world. My perspective is that I am much less concerned about a replacement movement that is consistent with original parts than I am reproduction faces/canisters and face/canister mismatches - e.g., Telechron face in a Pam canister - being sold as "vintage". I would consider the former vintage while the latter is definitely not.
