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.
I am glad the notes about Wolf came OK to you. I have not found any more about it so far but there maybe reference list in a Journal about 1927 or 8. Did you own or see one of them? They were a special job turned out to beat the oil engines for farms, by using wood or anything for fuel, hence the oval firebox to get a big grate. I have often wondered how they got the economy off the single cylinder piston valve engines, but the high super heat did help a lot and varying cut off.
I have had the IRON-MEN ALBUM for years now, but I wish I could get some early issues to complete my set for binding and I don't like a lot of loose copies about. I've picked up a few but it is not easy to get them. Do you take Tom Smith's Engineers and Engines at all? I have all the issues although dollar balance makes it all too costly, otherwise I'd have had Steam Engines as well, the California one.
I am a boiler attendant, now on a set of low pressure coal fired boilers (underfeed stokers). I can't ride on trains due to sickness and envy the folks who can look out of the windows. I can't. Get sick in no time. I've written to Elmer a couple of times, but he is too busy. I doubt that he can ever reply to half his letters, so I'd rather send these notes to you about the Wolf, else you would never see them, I am sure. If you do come on anyone who has any old early IRON-MEN ALBUMS for disposal I'd be glad to know please, but: I have to be away for about six weeks in June and July. If you are keenly interested in the Wolf, let me know and I'll try to find something for you, although it is very doubtful now. I've spent all my time hunting and recording steam engines and catalogs too, and now have over a hundred catalogs bound into volumes. They make a nice set, mainly stationary engines, though.
Reply: I get about $35.00 a week, and work 60 hours, but tax and insurance take $5.00 or more out of it. But we manage along just the same, and I've got a motorcycle. The only thing I can ride as I go so far and stop for a rest and then on again. This is second time I wrote this. First time was at boiler house when it was warm and I had boiler shut down, and I posted it with only your name (no address) on it so it came back to me. Anyway, I'll try about the Wolf, to get more, but it's queer you got a line on it and I did wonder how? All the best.
