Single vs double jackpot mills silent machines

[captkid]

For the experts out there - any rhyme or reason for this ????

I see mostly double jackpot mills silent machines - lion heads , castle fronts, war eagles, bursting cherry etc -

but few single jackpot versions of the machines? (I Love the War Eagle single jackpot version! - scarce!)

Was this an option that operators could order - Did Mills produced single jackpot versions for limited times, or did the operators prefer to not show the reserve jackpots for some locations and ordered single JP versions ??

The later 40's versions were produced as single small window and large window in greater numbers and both are more common - I Just don't know why?

I know the single jackpot castle front was produced as a separate model (Blue Front) but the others were not marketed that way

Wondered this for years and never asked anyone - Just would like to know history of this if anyone knows - Thanks!

Mills had single jackpot units with reserves that you could not see like the Poinsetta. They ran the single up to the War Eagle using similar type cast aluminum housings as the Poinsetta. The new jackpot they developed was a removable unit unlike the earlier cast units. This had the reserve on display above the main jackpot window. However many operators did not want their customers to see this and wanted the reserve window removed. This would have been too costly so Mills came up with an insert for the upper reserve window. The insert was screwed onto the jackpot window spacer, with two holes in it and would be put in before installing the jackpot. This was done to stop the operators complaints and was a quick and cheap modification for Mills.

I understand the removable jackpot for the silent line

What i was interested in was the single jackpot window castings that were produced in limited quantities and the reason for them on the early 1930 Mills machines
seems that not many were produced and there quite scarce

The war eagle and the lion head for example were made in single jackpot window versions (this is without the block off plate that that could be installed on the later double jackpot versions

maybe someone out there knows why mills made them and why in such limited quantities
