Interesting topic 2 dogs,
Thought I'd chime in with some personal observations and musings.
The standard stocks are just right for me although mine are kinda plain Jane. Others were offered, Ivory, Stag and fancy woods but I was trying to stretch the funds at the time and opted for case hardnening. Ten years later I had Paul Persinger fit it with some of the most georgous ivories I've ever seen.
A couple years ago, I found a pair on Ebay, some nice fancy walnuts with the s/n 9 embossed on the backs. I've often wondered why/how they got separated from the original gun. Seems real strange. I've not seen nor heard of anyone else finding/selling TLA stocks.
Being s/n 9 you'd have to think it was one of the earliest guns.....except for the fact Grover offered the buyer the option to personalize his gun with the s/n of his choice. This feature clouds the research on how many TLA's were built. On my TLA, I chose to have Grover select the next available number in line (K140).
As a side, the #9 stocks do not fit my gun. They are of a slightly different shape which leads me to believe Grover worked with different frame patterns. Also, #9 is drilled for one pin hole where my frame has two.
I'm always interested in TLA discussions.
