Dick - I think this photo by 'Darylg60' clearly shows his front base to be mechanically held in place and not Springfield work.
Daryl is developing a 'good eye' to spot the 'crimp' in his hand-guard's spring-clip, which suggests the hand-guard is likely improvised from a model 1892 guard.
(I reviewed Daryl's first posted pictures. One shows that the rear of his hand-guard has the distinctive contour of the model 1892 wood guard).
