In the IRON-MEN ALBUM of March and April, 1958, page 22, is a pix of an engine that I sent to you to see if any one could identify for me. Since this issue came out I have received a letter from a gentleman by the name of G. Watkins, who lives in England, with the following information. I will appreciate it very much if you will print it in the IRON-MEN ALBUM as he seems to know what he is talking about. He is a subscriber of the ALBUM.

Dear Mr. Cox:

I recognized your engine at once, although I had only seen an illustration of one. It is a 'Motor wolf', type M. F. 6 made by R. Wolf, Magdeburg-Buckan, Germany. It was a special high economy portable introduced by them about 1925-6, and gained the Silver Medal in the New Implement Class at the 'D. L. C.' exposition in Breslau, Germany, 1926.

Working pressure, 225 PSIC; Normal load, 26 hp.; Highest normal load 35 BHP; Peak, 50 BHP; Consumption steam, 14.3B. HP hr.; Coal, 2 lbs, weight about 2 tons 500 RPM; Flywheel 2'6' diameter. x 77/8' wide; Grate area 6 sq. ft. 36 inclined cross water tubes, large multiple coal super heater in smoke box. Two Sellers balance safety valve (yours still has them on it). Steam raised in 20 minutes, oval or flat side-circular ended firebox stayed at sides. Bolted joint on shell at firebox and top to allow shell to be taken off. Steam (lance?) for tube sweeping exhaust to chimney for draft. Feed pump and injector. The engine was a simple piston valve (4 rings on valve) crankshaft governor, varying cut off, reversible by shifting the eccentric when stopped, probably by bolt and flange. Enclosed splash lubricator.

I only got one leaflet on it, and little else was heard of it here. I looked up German made directory last night (IRON-MEN ALBUM came yester day) and the phone is not in there for 1956. Maybe it is in Russian zone. I don't know the limits of that. But anyhow, that's a bit for you. I don't think it was shown here much at all. Will try to find out in Journals but it's a long job to do that. Anyway, that's a start. There is no doubt that it is. Have you seen one at all? Wolf firm was early in developing the well known Loco mobile.
