Hello,
On the "Baby Austrian" in the SCWB2 section 08-045 or 046, one is from the collection of my friend Skip Mayorga (-045) and the other is from my friend down south in NOLA (-046) which show a difference in the diameter and the cavity cavity with both bullets coming from the Princeton, Arkansas area.
I believe Skip would be the better judge and authority on this bullet than I but I will add my poor comments on what I do know.
The bullet in the RB vol. 4 I can not comment on but I can comment on what bullets are in the museum in Tyler, Texas.
I saw no bullet that looked like the bullet -045 or -046 in the collection there in the museum. Unfortunately I could not get better pictures or measurements due the fact of the security of the case in which they were displayed in.
They had the following bullets which were found in a warehouse type building being rejuvenated as a private office complex (I think that is right). The following types of bullets are on display there the 69-caliber "Louisiana Troop" bullet "SCWB2, 09-023, McKee and Mason 291 & Thomas and Thomas 194 &
SCWB2, 09-031, McKee and Mason 313 & Thomas and Thomas 206b and they had 69-caliber round ball, a couple of 577/58-caliber 3-groove elongated ball and as far as I could see no thick base on either bullet and they had a 31 & 44-caliber revolver bullets along with some buck shot on display.
Please pay attention I do not believe all the MM 291 bullets were made there but have no proof of them being made else where, perhaps Shreveport or Little Rock prior to its occupation. I do believe the bullets were made in Marshall, Tx. & transported to Tyler, Tx. for cartridge making.
I hope this helps a little as I will when time permits me to look up this information for better clarity and explanation on the bullets of Tyler, Texas.
