Hi Keith,
I have to agree with you, the L&MV locos are simply beautiful!
They were built by Kitson & Co. to a design by ER Calthrop. Calthrop was the British engineer who built the Barsi Light Railway in India. The L&MV locos were based upon the design for the Barsi lines's 0-8-4T locos. The Barsi also rostered a number of very similar 4-8-4Ts. One of these locos survives on display in Secunderabad.
Its an interesting mental exercise to consider how locos with these various designs would have fared on the Maine Two-Footers.
Best Regards,
Glenn
