Marvel Unit 1 date code / serial numbers

Does anyone have a list of or link to dates of manufacture for the Marvel Precision Unit 1 conversion kits?  I can’t recall when it was that I purchased mine.  It’s a non-lock back with a serial number beginning with F followed by four digits. Came in a flat tan nylon zippered case, metal magazine, “slide stop”, wrench, and a badge holding the test target.

Many thanks in advance.

Mine is from August 2004 and starts with a "D". I'm not aware of any serial# lists but would be curious if someone had one.

Mine is F and four digits too. Im on search of original paper but i can remember was purchased in 2006 by the original owner. The conversión came with two ribs, one for scope and other with iron sights and the back sight hace the letter M.

I’ve had 3 “F” serial number Marvels that I believe were all 2005-2006.

I’m going out on a limb. D could be 2004. If E exists, it might be 2005. Leaving F as 2006.

 My F conversion was purchase by original owner in July 2006 and was shipped from Marvel in Crete, Nebraska.I think was the era of the shilen barrels.

Yes the F slides had Shilen barrels. I RR 3 of those conversions on the same day with 3 different brands of ammunition back in 2009ish. All 3 ranged from 1/2”-5/8”.
Those barrels always shot well. I shot 100-8X SF with that conversion. It shot 9/16” with cheap bulk Federal AutoMatch. That ammunition eventually went to crap a few years later. Shot many 10X clean short line targets with it. 
I ended up selling that pistol to a friend and recently picked up another. They were all long slides by the way.

Nice data, Thanks Jon!!

Gee I must have one of the rare ones. My unit which I bought at Perry from Bob himself is unit B0762 and the badge 50yd target is measured at .350".
I think it has a micro grove barrel.
