Hello There,
I am a Disciple of Shi Yong Wen in Kaifeng. We have 2 monkey sets you may be interested in. I am certain its not the exact one you are looking for, but it should be interesting nevertheless. The set is mainly striking movements with the relaxed monkey hand and the monkey paw. It has a few xiang xing movements, i.e most of the blocks use the 'shading the eyes' movement. Here is a Video link, it appears about 6-7 min in, but i think you will enjoy the whole video.

The set is called 'Da Sheng Xing Zhi' ....I think.... It refers to the great pilgrim, almost certainly a reference to SunWuKong the monkey king. There is an accompanying staff form, also more practical than theatric, also with two sets. My master is now nearly 70, his father was a famous Martial Artist in Kaifeng (shaolin Pai) and in his younger days travelled over china to find good masters. He learned this from an old man in Tianjin who in turn learned it from shaolin when he was young. I am not clear if it is from shaolin temple or from dengfeng county, but it is shaolin pai.
We also have Yuan Hou Bang, but this set has no monkey like moves what so ever, just the name. It should also be noted that the Shaolin Temple Tong Bei Quan (now referred to as 'xiao tongbei') is descended from a monkey like form (tong bei yuan quan). Even today some versions of the set still have a slight monkey feel, i.e the first move xu bu is done with monkey paws in some versions. Also when you turn to the side with a block after xie xing some versions shade the eyes like in a monkey form. The current version as was practiced by Xiu Xi and now by Deyang has no monkey reference. Many forms called Tong Bei are descended from Tong bei yuan quan.
Shi Yong Wen is recovered from a recent illness and is now accepting foreign disciples....He in his time has trained under great masters such as Degen and Wu shan Lin. If anyone is interested in training here please reply to me.
