Bill Finch asked about a list (catalog) of Wurlitzer style 150 rolls.

There are complete lists of all three major Wurlitzer music roll
styles.  Mike Grant has a print catalog of style 125 rolls.  I have
my on-line 165 catalog, which includes also a small list of Style 180
rolls.

Jack Conway has a print catalog of 150 rolls.  I have a print catalog
(not so graphically pretty) that I plan on putting on-line when I have
found good software capable of indexing by various tagged fields.

Before I retired from the Library of Congress I did all the necessary
searching in copyright records to correct the not-infrequent title and
composer errors that one finds in the raw Wurlitzer data.  This has
been done for both Mike Grant's 125 catalog and for my 165/180 catalog.

I started last winter to input on-line the title index of the 150
catalog, which runs to over 2000 titles (there were more 150 rolls
issued than any others), but the freeware I tried to use was sooooo
clunky I gave up after inputting 15 titles.

I used to distribute copies of my 150 data but photocopying costs
(there are 150+ pages in it) make that undesirable, now that I can't
make copies at government expense.
