Some notes on the Goodell-Pratt catalogs - complied with thanks to Michael Bishop in the United States. A fuller account of this work will be published later.

GP catalog #7, 1905: The Model 29 polishing lathe is present ($7.50) but shown with no accessories. The Model 29 catalog picture doesn't have a notch in the large pulley for drive by a round cord, but the text does describe this feature.  The Mass Tool Co. catalog is listed as being available separately.

GP catalog #8, 1907:  Model 29 1/2 polishing lathe introduced ($10.00).  Described as identical to the 29 (still at $7.50) but with a better tailstock and improved minor features.  However, this appears not to be correct as the casting is clearly different in the representation in the catalog - being braced and ribbed like the Mass Tool Co. lathe - and weighs considerably less than the 'smooth' casting of the 29 - other small discrepancies are noted as well.

A catalog picture shows what I'm calling a "v1" logo, that has different script to the later incarnations. No accessories are sold separately.

The Model 125 lathe is described as being introduced ($20.00). "This 24-inch Bench Lathe, with a 7-inch swing and 12 inches between centers, will be welcomed by a host of our customers who have insisted on ordering such a machine from us years before we had any idea of making one.  The cut [picture] cannot fail to convey an excellent idea of its general characteristics.  It is an Amateur Bench Lathe, and while all its construction and fitting is done with great care and reasonable accuracy, we do not pretend that it is possible to make a precision tool for the price at which we propose to sell this one.  But we do know that there are innumerable uses for just a machine as we are bringing out..."  (the text changes in later catalogs)

Precision lathes no longer appear branded explicitly as the Mass Tool Co.

The first catalog released by Millers Falls post-GP acquisition (MF #41) does still include the No. 125/494 bench lathes and one attachment, the No. 132 slide reset.
By the time MF#42 was published, nothing was left of the Mass Tool Co. parts
