Item History & Price
Reference Number: Avaluer:4321270 | Country/Region of Manufacture: United States |
Featured Refinements: iron meteorite |
For auction approximate dimensions: 207.5gm x 5cm x 2.8cm x 4.5cm. Found by my lovely wife Sheila (me being the completely adequate husband) in 1992 on the farm of Mr. T. Tuttle j...ust east of West Bend Wisconsin. We got interested in meteorites when living in the Chicago area and started searching in places Mr. H.O. Stockwell had some luck (including Brenham, Kansas). To find out who owned the property I put an ad in the West Bend paper and got a call from a landowner that said another fellow (R. Reisner, sp?) had been searching the area and knew about the meteorites. Sheila found a 450 gram specimen sticking halfway out the ground. We had a 50:50 agreement with the landowner so I cut it in half to honor our promise (no contracts just trust, imagine that). I cut a couple slices from our half, polished and etched, coated with an acrylic polymer (can be removed with acetone), this is the left over end cut. See below for description of Trenton from Handbook of Iron Meteorites. Included an autographed photocopy of Sheila with her find and a photocopy of my newspaper ad receipt.
I know a lot of new collectors have not heard of us but we've been working with meteorites for over 25 years, check out our videos iffen you don't believe me:
You can see Sheila holding her find in this video: Short youtube video on our Brenham, Kansas efforts!
How to metal detect a meteorite: How to metal detect a meteorite
and we have more videos on the youtube.
Sold only as an item for display (why? because over the years people have asked if meteorites could be used for some really weird stuff, you wouldn't believe it or ever think of some of these things, gotta love it).
Always practice good hygiene and wash hands after handling. Thank you, Donald I. Stimpson Ph.D.

Buchwald: Long believed to be a rather smallfall, it was recently proven by Read & Stockwell ( 1966) that theTrenton shower comprises several large specimens, too , so that today13 specimens totaling 505 kg are known .The first four masses were plowed up byLouis Korb before 1868 and were described by Brenndecke (1869) andSmith (1869). Smith gave the location as the town of Trenton , which, however, should be the township of Trenton, about 45 kmnorth-northwest of Milwaukee and 8 km southeast of West Bend. Thenext two masses, Nos. 5 and 6, were plowed up later, in the samefield , and were described by Lapham (1872). These specimens weresomewhat cut and distributed , mainly through J .L. Smith, around1870 and Ward's Natural History Establishment after 1892. Almost allexaminations published before 1965 have been based on material fromthe first four. Brezina (1880b) described the Reichenbach lamellaeand gave a photomicrograph. Later (1885 : 211) he used Trenton as atype member for the Trenton subgroup in his classification system .Perry (1944) gave excellent photomicrographs of the crosshatchedkamacite and Wood (1964) examined the kamacite-taenite re lationshipwith the microprobe and gave several photomicrographs. El Goresy(1965) examined a troilite nodule . Axon & Boustead (1967) andAxon et al. ( 1968: 535) discussed the shock-hardened structure inmore detail and presented photomicrographs of twinned troilite.In the meantime it had occurred to H.O.Stockwell, of Hutchinson , Kansas, that the area might yield morespecimens if searched with his wheelbarrow-mounted electronic metaldetector. He identified the old 40-acre Louis Korb farm, now owned byReuben Gauger, and by systematic searching in 1952 found two largemasses, of 187 and 239 kg , respectively. They were buried under60-65 em of earth (Read 1962; Read & Stockwell1966). The authors, in addition, found the small specimens Nos. 12 and 13 , and receivedinformation on Nos. 7-9 which had been found previously. Inunpublished notes from 1868 (IA.Lapham 1962) Lapham stated that"other fragments are said to have been found, which have beenused by blacksmiths in the neighborhood ." Thus, more than 13individuals have been recovered from the shower.All masses have apparently been foundclose together, within the same field. According to Read &Stockwell (1966), who presented a detailed map, ten of the masseswere found within 30m of each other, while Nos. 7 and 9 were foundISO and 300m, respectively , farther northeast. Trenton thus forms anunusually dense shower.Herr et al. (1961) examined the Os/Reratio and estimated that Trenton, as most other iron meteorites, wasformed about 4.5 x 109 years ago. Schultz & Hintenberger (I 96 7)and Hin ten berger et al. (I 96 7) presented data on numerousoccluded, noble gases. Vilcsek & Wanke (1963) estimated thecosmic ray exposure age to be 450±100 million years; whileLiimmerzahl & Ziihringer (1966) found 6 70±220 million years.Voshage (I 96 7) found, with the reliable 40K/41K method, 575±60million years; while Chang & Wanke (1969), with the 1'13e/ 36Amethod, found 410±50 million years. The latter pair of authorsestimated the terrestrial age to be lower than 105 years because both36CI and 10Se were present in significant amounts. Buchwald ( 1971 d)discussed the gas content and the metallographic structure andpresented three photomicrographs.
