That's ok for a quick fix, but problems arise if one ever decides to sell the vehicle. Same for the states that dont require titles. It creates big problems for us slobs that live in states that require them. So in that sense it eliminates potential buyers.
What problem for a buyer? "Here's the engine you need to prove out the title. Just tell them the old engine wore out and you found this one to replace it."
More than likely the sale transaction will be completed without ever having it officially verified. And if it is - there is the pallet with the number you need.
80 years covers a lot of official ground.
As to "marketability" - yes those of us in states without title requirement COULD have a problem with a sale.
I had exactly that problem selling a 1930ish AA "rolling chassis" to a buyer from Texas. (Nice chassis - 26K original miles - engine loose but ran nice - and the chassis still had a lot of original paint on it and ALL those small springs and nuts and washers that tend to get lost or rust off.)
As it turned out I was able to have the chassis "titled" by Cow Hampshire by showing them the original bill of sale (from a Connecticut seller) which showed the details - particular of which was the VID.
I filed to NH for a "replacement title."
"Oh you don't need that because your vehicle was made before 1999"
"Oh yes I do because I need it to sell the vehicle to a buyer in Texas which does have Title Law."
"No problem then - fill out the paperwork, send in the $15, and we'll contact you when we can send out an official agent to verify the VID."
The pretty Officer in Blue arrived in a local PD police car. I think she was a trainee or possibly admin clerk in our local constabulary. We verified the numbers (both frame and engine which fortunately matched) She knew nothing of Model A numbering - until I told her (being the outstanding citizen that I am.)
Four weeks later the Title arrived in the US Mail.
Five weeks later the Texas buyer was in my driveway with a trailer.
