Is there a mod or method to limit quantity of a specific part for a save?

Back in the late 1940s, American space exploration got a huge boost, not just from the German rocket scientists (Werner Von Braun, Willy Ley, etc.) who were "invited" to come to this country, but from the stock of completed and partially completed A-4 (aka V-2) rockets that were captured.  Those rockets formed the basis of much of the early use of rockets as science tools, as opposed to weapons.  They were far ahead of anything America (or Russia) had of their own, capable of reaching space right out of the shipping crate.

The only thing was, there was a limited number of those rockets, even fewer spare parts, and some of the parts (specifically in the engine) were subject to aging effects that made them less and less reliable as the years after 1945 added up.

Is there a mod or setting available, ideally for use with Scrapyard and Oh Scrap!, that would let me put a limited number of A-4 engines into my inventory, and when they're gone, they're gone?  Having, say, a couple dozen of those but with the knowledge that once they're used up (destroyed in accidents, not recovered, etc.) they're gone would be an interesting add-on for the early days of an RO career.  A means of having their reliability drop off over time (due to material aging) from early 1951 (should be 1946, really) would be even cooler.

Yes, sure, the RD-100 is an exact copy.  Except it isn't, quite.  It's dimensionally identical, and its performance is essentially the same, but it used different materials that were more available in the Soviet Union than what the Germans had used in 1940-1945 during the development, testing, and operational manufacture of those engines.  I'd like to be able to introduce the RD-100 as what it was -- newly made copies of the A-4 engine, developed as the stock of actual A-4s dwindled.

I know this is an old thread, but hey-- I'm catching up on old material...

What comes to mind for me is creating an unresearchable/buildable engine part that then gets added to the scrapyard inventory. Not at all sure how to deal with that.  The scrapyard inventory I think gets added to the persistent save file.
