Arming the Suckers by Ken Bauman (Morningside 1989), pp.105-07, from your local library or better yet find a used copy online.. Great resource for Illinois units and well worth the price.
The 32nd had quite a variety of arms. Started off with smoothbore muskets altered from flint to percussion, augmented by 170 "French rifles" in early 1862. By the end of that year they had 230 .577 Enfield Rifle-Muskets, 36 Dresden & Suhl Rifle-Muskets and 11 U.S. Rifle-Muskets (possibly m.1855 but more likely m.1861's). Varied somewhat quarter to quarter thereafter, and with small numbers (18 to 40) .58 cal. French Rifle-Muskets with triangular bayonets or .577 French Light Rifles (aka Liege rifles). From 2d Qtr 1864 on they carried almost exclusively U.S. Rifle-Muskets (Springfields), probably m.1861 or m.1863 but precise model is not specified, along with a few odds and ends.
Bauman predominantly relied on the summaries the Ordnance Bureau created from individual company quarterly returns. Those are available from NARA as Microfilm Publication M1281 (now available digitally for about $125 per "roll" (eight "rolls" total of which 5 cover the infantry, 2 the cavalry and 1 the artillery, for U.S. Vols. and Regulars). Seven or eight quarters are covered (can vary by state) beginning 4Q62. While a very rich and fairly comprehensive resource, the summaries combined multiple arms and models into single categories so can lack specificity. They also can contain transcription errors (such as the switching back and forth in different quarters between the different French weapons -- that is likely due to transcription errors by the Ordnance clerks). Note also that not all companies reported all quarters (or returns were lost), so in looking at regimental totals always check to see how many of the ten companies actually reported that quarter and adjust accordingly to make a full regimental estimate.

I’ve read that the Spencer carbine was highly prized by cavalry soldiers, but it was not issued to all of them. Would it have been possible for a soldier to exchange their weapon for a better one like the Spencer?
