The tender, the backhead, the firedoor, and of course....the FIRE! This 3-1/2" gauge 4-6-2 will pull a few adults or several kids.....and will provide all the thrills of small-scale live steam operation that the hobby's pioneers, and those who came later, experienced and enjoyed for decades.
Designed by H.J. Coventry in the late 1920s; updated 1960. Friends Yankee Shop Models will produce this design (rough castings) if YOU want it to return!

If you are interested in "rough castings" for the FINEST 3/4" scale model of the Pennsylvania Railroad K4 "Pacific" that has ever been designed, the H.J. Coventry 3-1/2" gauge K-4, then please make your desire known to Friends.
Castings for this locomotive have been off of the market for almost 50 years, but will be produced if there is enough interest in its return.
Are you one of these persons?
Cost for a complete set of brand new, top-quality, made in USA "sand castings" in iron, bronze, and aluminum (EXACTLY the same as formerly available from H.J. Coventry):
$3,995.00
If you'd like this design back on the market, may I ask that you please make your desires known to me. Please participate in my "K-4 Survey" by clicking HERE. The survey is so that I can determine how many people are seriously interested in these castings' return. You will incur no financial obligation by participating in the survey.
The survey went online October 28th, 2009 and will be online for the remainder of 2009 and into early 2010 (if required). The survey will be taken down in early 2010 if there is not enough interest by that time.
If by early 2010 the survey indicates to me that enough people are interested @ $3,995.00, then in early 2010 those interested will be asked to supply a 50% deposit ($2,000.00) for the castings.
If enough people supply deposits, the required pattern and foundry work for the K-4 will commence (in early 2010) and the castings will be produced for the first time since about 1960. The other 50% balance (approximately $1,995.00) will be due when the castings are ready.
If not enough deposits are received, then your deposit will be returned and no pattern or foundry work will commence. For example, if 10 people are interested but only 5 send deposits, then your deposit will be returned in full and no pattern or casting work will commence. This design's return to market depends on serious interest by a substantial number of persons, and their wholehearted financial support.
I thank you very kindly for your interest. Please take the survey if interested in the return of the K4 castings.
