Missing Notch

Description from Cubicdissection:

Missing Notch is one of Stewart Coffins more difficult assembly puzzles. The six pieces are nearly identical, with notched out centers and two angled notches on the outside. One piece is missing an angled notch, which obviates the obvious coordinate motion assembly. Can you figure out the alternate methodology?

Over the next few weeks i will be selling off my entire collection. I have been collecting for almost 10 years, and also have some rare puzzles. Most of my collection is wooden puzzles, but a few metallic have sneaked in too.

I can offer to hold your won item, and combine it with other current or coming auctions, to save you on shipping.
Having sold many puzzles on the Cubicdissection marketplace (https://market.cubicdissection.com/display-feedback/keezor), i have a lot of experience packing and shipping puzzles, and so far have not experienced any damaged shipments.
I take great care to pack the puzzles, so they can withstand the brutal handling the packages often get.

Shipping cost is calculated after the auction is finished. For 1-4 normal sized puzzles, expect around 15-20 EUR with tracking for most countries.
Payment by Paypal(fee 5%), Wise(fee varies, cheaper than paypal), SEPA/EUR(no fee), Bank transfer is accepted. 
Fees will be paid by the buyer.

I can also offer split payment, where you pay 20% of the order now, and the remaining next month. I will ship the puzzles, when they're paid in full.
