Lake Winnipesaukee R.p.o. Cancel Question

I have this postcard(used as a vehicle, no adress, no text on backside) with 3 Lake Winnipesaukee RPO cancels.

The bottom left one I can find on google.

I am not sure about the 2 other ones.

The top one has an upside 5 and the lower right has Winni(n)pesaukee misspelled.

Are the top and lower right cancel right?

Thank you for your help

Very common for collectors (especially RPO collectors) to send cards to get canceled as souvenirs for their collections. They typically got several identical cards canceled and then mailed back under cover. That said, these philatelic cards are often the only common way to obtain cancels from the mid to late 20th century RPO routes. The machine cancel at the top is a Universal Model-K, a small hand-driven machine. Markings with typographical errors are uncommon, but not typically valuable. And yes, the Railway Mail Service administered these water routes too.
