These planes, used to start a moulding, were produced and sold in matching pairs so as to overcome grain direction.
The 1861 MARPLES Catalogue lists them as ‘Snipes Bill‘{singular}:
The 1873 Catalogue now gives them item numbers and changes the name to ‘Snipe Bills‘{pair} :
Both Snipe Bills and Side Snipes appear in the 1888 Catalogue as #1053 and 1055 respectively.
The 1897 listing is below, showing new Item numbers:
1909 shows another number change:
They are omitted from the 1921 Catalogue but re-appear in 1928 [below], but that was the last catalogue reference that I can find for Snipe Bills.
In no catalogues can I find an illustration of Side Snipes. These tools had an almost vertical side cutting edge and were used, as were Snipe Bills, to trim and clean up mouldings and Snipe Bills could also have been used to start a moulding. They were generally sold in pairs so as to deal with grain direction. A pair of Side Snipes is shown below:
