Maybe Westra and Sharp didn’t mount any scopes on 40-inch rifles because they never got an order for one. Do you have any evidence that they ever did?
Anyway, here's some evidence from Sharp himself and as an added bonus, some extra logical conclusions from myself.
1.
Oswald’s choice of weapon aside, there was something else to haunt him. At work the next day, Sharp relayed concerns to his boss about the gun he had seen on television.
“It’s my rifle, I put the scope on it,” Sharp told him. His boss replied, "'No No No, don't say that!'" Sharp said his boss was afraid of the consequences. https://web.archive.org/web/20150806005342/http://newsarchive.medill.northwestern.edu/chicago/news-226036.html2. Both Sharp and Westra in the same HSCA interviews agreed that Kleins mounted scopes on the 36 inch model but for some reason the 40 inch model which was advertised for almost a year in multiple Gun Magazines never had a scope mounted? Really?
Perhaps if it wasn't done by Kliens, it was done out of house?
3. America is full of Gun Enthusiasts and after the Scoped Carcano became one of the most notorious rifles in America it's difficult to believe that there wasn't at least 1 Gun Enthusiast who would want a similar Scoped Rifle. To at least check out the difficulty of the shots or as a souvenir. IIRC Walt said he has three Carcano's with at least one with a scope?
4. Holding inventory is a costly business and if an item isn't selling, it only makes sense to lower the price but the price of the combined package was the same until at least the December Kleins ad that I showed.
EDIT I just came across this piece by Gil Jesus, who posts some bizarrely irrational opinions and even he doesn't lower himself to the extreme nonsensical speculation that you just spouted.
"Maybe Westra and Sharp didn’t mount any scopes on 40-inch rifles because they never got an order for one""It's clear from their ads that Klein's was offering the 40" rifle with a scope. But the evidence indicates that the scopes were not mounted "in-house"."https://educationforum.ipbhost.com/topic/27197-10-reasons-why-i-believe-that-the-depository-rifle-isnt-oswalds/JohnM
